Dark place

im in such a dark place in my life right now. i had a messy breakup 6 months ago, he started dating someome else immediately, now hes back and we're talking and stuff, hes been pretty mean to me n ive been through a lot. my mom is physically sick and depressed, sucks to be at home. i havent studied in months, exams are stressing me out but i cant get myself to study. ive put on a lot of weight and my confidence is at rock bottom. ive been avoiding meeting and going out with my friends. i feel tired throughout the day and cant sleep at night. my head hurts and i hate everything. people are talking and shouting around me but nothing gets to me. its like im stuck in time. ive become short tempered and snap at everyone. ive never known to express my feelings since i was young, so i deal with everything on my own. nothing makes me happy anymore. i hate what ive become. i thought i was strong enough to get through something liike this but apparently not. im so stressed all the time and im not getting anything done either. people say it will get better, but will it really? will it? its been getting worse every day and i can see no light at the end of this tunnel. sucks. sucks so bad
