What does my upcoming Rahu Dasha hold in store for me?  Will benefits gained last?

Greetings.  My birth information follows:  
       birth date:  January 25, 1969
       birth time:  22:30
       birth place: Trivandrum, India
My chart:
       (is attached below)

Through my childhood I was very successful in my studies, was very much esteemed in society for my talents and character, had many admirers, and also enjoyed career success as I started my career.  Then got married (arranged) – though horoscope matching seems good, love and friendship never formed between us.  Just over a year after marriage, my sade sati started, so for the majority of my married life, I suffered very much due to this.  (Since I was born during sade sati, this was my first complete sade sati, and therefore, I understand it is considered my first.)  As my Saturn and Rahu are in my 7th house in the sign of Pisces, and my then husband’s sun was in Pisces, I believe this may have made it even more difficult, and the disappointment in my marriage even more severe – my guess – I’m not sure.  During the final two years of joined married life, Mars Dasha also started, after a prolonged separation, divorce is now complete.  (Sade-sati ended almost simultaneously with decision to separate, six months before actual separation.)

During my adult life, I have met and endured many hardships and disappointments – in personal and professional life, and some scandal, due to no fault of my own.  I feel as if there have been short periods of relief only, but not any success.  Recently I have also faced a job loss.  I have a positive attitude, that what was not good for me has ended, and what will come in my life will be better.  However, this is blind faith.  I’m eager to see what my chart says.

Mars Dasha will end in November for me, and Rahu Dasha will begin.  Rahu Dasha is something that naturally instills fear.  My experiences have made me stronger and more resilient, however, I really wish to have some enjoyment in life again.  It feels that the suffering has been too hard, and for too long.

I would appreciate if any and all knowledgeable people would comment on what Rahu Dasha holds for me.  As many details as possible in each of the following areas would be very much welcomed and appreciated (first two are most important for me, also any areas I have forgotten are also welcome):
   1.  Area of career (please, many details)
   2.  Area of marriage (please, many details)
   3.  Area of children (hope for me yet?)
   4.  Area of health
   5.  Area of wealth
   6.  Further Education

I have read general descriptions of what each dasha period and bhukti period should bring, however, I wish to know specific to my chart.

My other important question is that I have read that whatever is gained during Rahu Dasha will also be lost by the end of Rahu Dasha.  Does this refer only to material related gains, or also to marriage?  There is no such person in my life now, and I do not wish to rush in this area.  If I marry during Rahu Dasha, will the marriage end before the 18 years are over?  If children are born, will they die?  

(Does my chart indicate another marriage?  I never felt the first was a marriage – no friendship, loyalty, love, caring, etc. – it was enmity and betrayal – very painful for me.)

Many, many sincere thanks to all who take time to respond!

though i'm not an expert, my knowledge says that RAHU & SATURN are karma planets who give complete results (good/bad) during their periods

you've both conjunct and rahu dasa will seperate you from parents/family, make you find new ways of living, will create disputes with close pals and relatives, starting a new career, frustration, living for few days in isolation, strange dreams, inclination towards spirituality

Thank you, Phantom, for your valuable comments!

May I make another request of you?  I was admiring the details you had given P1027 regarding details of marriage.  I'm assuming that possibly since this would be a second marriage for me, one may not think of looking in my chart for such details.  However, I had discussed this with another person who is knowledgeable in vedic astrology as well, and I had given him some more details regarding my marriage (since that was a private conversation), and from what I had said, he drew the conclusion that my first "marriage" had never indeed been a marriage, but rather a bad business arrangement, since no mutual love and deep heart connection was ever formed.  In light of that information, looking at my chart, he said that it indicated a late marriage.  

I do not know what the generally accepted opinion would be regarding this, or if there are any clear guidelines in vedic astrology regarding this.

In light of the above information, would you be able to tell me anything regarding marriage, children, etc.?  Also, I'm very much interested in understanding how you come to the conclusions, as much as I'm interested in the conclusions, so would appreciate as much detail and explanation as you can give.

Also, can you give me any details regarding the new career?  I've been considering changing fields for sometime now, but as the field I would be leaving is a good one, and as I've not ever been 100% sure about the next field, I've been hesitant.  Do you know when my career related changes/confusion/decisions will finally be settled?

Thank you again!

taking into account planets degrees, constellation in which it is placed, constellation owner and those degree's sublord

all these will give exact predictions

whether there's love or not, 1st marriage has to be counted
(there are many couples in this world still living together without any love. they're just doing business)

2nd marriage will be a better one

Please, respected gurus, may I request some of your time?  

I wish to know what are going to be the effects of Rahu Dasha in my life, according to the influences of Rahu and the other planets in my birth charts.  All of my basic details, birth chart, and specific requests are in the original post above.  

However, as it appears that the KP method may be preferable to some, I am also including the KP tables and charts in this post for your convenience.  (I have the tools to generate the data, but neither the knowledge nor skill to interpret them.)

As many details as can be given would be appreciated -- nothing is too much!

And please, as I am also trying to understand and learn this, please give explanations.  Thank you VERY much!
