I don't think we (Cancerians) are prone to depression -but yes I think we do tend to think too much ...esp. about the past - which other signs like Aries and Leo seem to ignore.

Thinking too much can affect the body also ......I found that whenever I had a major exam or project where I was worried, my stomach acidity increased manifold .....
Even in normal circumstances , I have less ability to eat and digest spicy foods as compared to other care-free people.

i think we cancerian have tendency of thinking too much....we r so sensitive that if we are affected emotionally in some respect, it normally impacts our physical body as well...also we dwell in the past and keep on missing all friends and places...
it used to happen with me as well near the exams i couldnt eat that much and used to have nauseating feeling...

I believe we as cancerians have the hardest time mentally and emotionally because the we are controlled by the moon, just as the oceans are. we have waves of moods throughout the month. I have learned to prepare my self by what the the changing moon phases and setting my mind for what is to come. I have seen to many other of my cancerian friends on med's. There are other ways to control and embrace who we are, for the are so many aspects of ourselves throughout a month. we are like a faceted diamond with many sides. Take advantage of mood swings and shifts. Use them in a positive way. I write or draw. I have came up with many dark and depressing writings and original artwork. Go within your shell, but discover what is in there while you are hiding. Peace to all! Sataurian
