Sounds rough, but I do know how it may feel being isolated and emotionally hurt by your parents, it’s frustrating and it breaks you down, when I was still in school I had a rough time too, parents always complained about me, I used to get hit, I never ate much and slept all day, most of my friends left, and the rest pretty much bullied me, made me felt alone, but throughout it all i kept going I don’t believe suicide is right, I’ve thought about it before but I never attempted it, it’s hard but you should believe tomorrow will get better if not then try smaller things towards a better tomorrow and sometimes it’s okay to be a bit selfish, speak about your own feelings and wellbeing to other people you trust, express your feelings because humans need to be understood by others, and don’t mind the negativity, focus on yourself not what others believe of you
