Help? family problems?

Ok so first off im 14 in 8th grade i have a pretty good lofe. Have plenty of freinds and prety good social life. I love all my family members. Im an okay student in skool. Im in all highest honors classes on brains (im pretty lazy but ill get to th.at later) well i have a twin and we were both pretty popular and last year in skool i had pulled put most of my hair from anxiety and got made fun of and usually stayed as far away as ppl as possible. My brother was more social and gained more polularity. This year my hairs grown nak hes gone to boardin skool. At the beginnin of this year i was still kinda liked but since i was less liked they blamed me for him havin gone away and wished i had gone instead of him. Well i think ive finally gotten bak on track and on everyones side. But i was so focuaed on my social life that my skool work wasnt bein completed. I recently gotten a report card and the grades were bad. Now my parents are hardcore monitorin me and in communication with teachers. I told them that i was lazy and didnt do my hw and thqt i was sorry and was gonna try harder next quarter. Well now i am startin to do my hw buf occasionally i wont do some but its still improvement. But now that im doin my hw its still not good enough for them. We get in figths and i admit i am a bit rude but they just put me down and keep bringin up last quarter ajd sayin im not tryin at all and that im a failure at skool wen im tryin to have a fresh start. Im really tryin and improvivn. Now we get in huge screamin fights everyniht and i usually go to bed cryin even though ive donr my hw. Ive talked very deeply to them and have seen many counselers. I have started takin anti depressents and adhd medicine and feelin a bit better. Any advice? I really just wanf them to stop botherin me and let me handle this on my own but if i do they yell at me
