My HORRIBLE BODY

I've been struggling with myself for YEARS! And i'm only 18. I've always been more chubby than other kids, and I got made fun of but still had bunch of friends. Last year was awful for me, I lost a bunch of people and got very depressed. My doc prescribed me a bunch of pills and they made me gain 80 pounds. I hate myself so much since then, I just want to hide. I'm up to 260 pouds now and i've been trying so hard to lose it but i've injured my knee very badly and cant do sports anymore since a year. All I want to do is cry and cry and cry and today I looked at myself in the mirror from every angle an saw some stretch marks I haven't seen before and i'm shocked. I'm so disappointed in myself.

I literally don't know where to go from here i've tried calorie counting, fasting... I lost a few pouds but I need a drastic change, I want to be more healthy and be comfortable with my own body. Please, I don't want any hate but i'd like to know if anyone has advice or stuff that worked well for them? Im not expecting anything miraculous, I know I have to work hard but I don't know where to go from here. I'm broke and have no money for the gym, I dont have a car or public transportation either, I dont really pick the groceries at my house so im kind of limited here... please anyone comment down and let me know ❤️🥺
