I need advice on what to do

Hi, I'm 13F and I'm overweight, a lot of my friends make jokes and fun of me for it, but at the beginning of the year I lost all my other friends because I finally stuck up for what I wanted for myself instead of listening to them. So basically I've been working out for a month, 7 days a week. I'm so sore and so tired, my parents don't do much to help at all, the more of make suggestions on how to do it better instead of actually helping me. I've been feeling absolutely horrible about myself, I hate the way I look and wish I was a different person. I've been slacking off the last two days and I started sobbing and of course my parents instead of giving me support just gave me advice on how to be better. I'm so stressed this years been really rough and honestly painful for me and I don't know what to do, like if I should keep going or not. I've seen results but they just kind of stopped even though I've been doing an hour of working out for a month. I'm so lost and I hate myself so any advice?
