depression

hey so ive been battling depression by myself for a while and idk what to do anymore.. every time i ask my mom about getting help she blows everything out of proportion to where i feel embarrassed for even bringing it up. idk who to turn to because i feel like I’ve pushed everyone away from me.. i feel so isolated and alone and i feel like everyone has left me because they gave up on me being happy .. i have breakdowns almost every day and the smallest thing can push me to have one.. this was all caused by an ex who was very physically and verbally abusive and told me he was going to kill himself and it would be my fault and when i saw him we would get into arguments and he’d push me and shove me and when i would try to leave he would grab my arm so hard it would bruise. ive also been sexually assaulted and harassed so much i just can’t take it anymore .. my parents aren’t supportive of me at all , when i said i wanted to be a doctor and go to med school they laughed in my face and said they wouldn’t pay for something i was just going to fail out of .. I’m just so lost at this point and i feel like i have nothing going for me anymore .. please help me ..
