My girlfriend is breaking up with me at the time i need her the most. what am i gonna do now?

i LOVE her. She's breaking up with me because she thinks im too emotional nd she doesnt have time for the drama. she says she has enough drama with her girlfriends. I was only emotional because my brother and my friend died at the same time and it's been really hard on me. my mind has been crazy. Then on top of that my parents are kicking me out the house because i flunked out of college. starting the first of next month i have to pack my bags and leave and i dont know where im supposed to go. I dont even have a car. I Have 2 fulltime jobs... EVERY ONE of my family members and friends are on my case.. everybody keeps saying im not good enough. i've been working my @$$, everytime i come home im tired as helllll. my gf was the one person who i thought loved me unconditionally and would never leave my side, cause my entire family is money hungry. but when i started crying she just up and left and told me she couldnt deal with someone so emotional. sometimes i feel like committing suicide. im doing all i can and nobody can see what a hardworking person i am. my gf's birthday was coming up soon and i was planning a huge suprise party for her and was gonna buy her a tiffanys ring, but now she is no longer in my life. someone please help me. I'm 23.
