hopefulgirl86....Here is a BIG ((((((((((((HUG)))))))))))))) from me right to you!!
First of all chrisdee is right....loving yourself MUST come first!
I see in your writing that you feel hopeless but I sense that you still have the "spark" and what does a spark mean? It's LIGHT my friend!!! LIGHT....it is there

Look deep inside and there you will find it
Also I get the sense that you actively "seek out" these people who you say don't like you or accept you....meaning it's not ALL truth...you have your self "convinced" that nobody likes you. Darkness also brings with it deception.
I can tell you as chrisdee said people are attracted to light not darkness... a smile not a frown...confidence not self destruction...these things can all be seen by others! The way you feel about yourself is projected in the way you dress, walk, talk, and live. It's all out there...everyone knows you are miserable and therefore react to your misery.
Things will get better once you find that spark...it will soon turn to a torch and light the darkened pathway to better things for you...
Think of the song...
This little light of mine...I'm gonna let it shine...let it shine, let it shine, let it SHINE
Think of the warmth of the sun...the beauty of the stars....the awe of the oceans...the sweetness of a newborn babies cries.
There is beauty in EVERYTHING created ...that's right...YOU too!
Since you enjoy writing...get out your note pad and write all the things you like and why you like them...
Make it pretty by adding color or adornments and hang it where you can see it often
Here is another big (((((((((((((HUG))))))))))) to remind you EVERYTHING created is beautiful!
