stressed out please help😭

Hey guys, so like this is a hard topic for me to talk about seriously with friends or family, but I feel like over the summer I drastically got more and more like sad and I basically saw no reason to live anymore. I was just always so down, and I was also (and still am) dealing with a very painful injury, that has been really taking its toll on me both physically and mentally. As my injury got worse I feel as if so has my mental health, but no one bothers to listen to me or take it seriously. (Even my doctors wont do anything to help) but back on track, so yeah thats been hard, and now that Ive started school up again, nothing feels the same, I dont (and also cant) participate in anything I used to enjoy doing. My classes have been so hard for me to even sit through, and Im starting to actually worry deeply about whether I'm going to make it out of highschool this year. On top of all of this, my home life has been the shittiest its been, my dad kicked me out a little over a month ago, Ive had to live with my mom who has severe BPD. I love her with all my heart, but its hard dealing with all of her abuse without a break. To be truly honest, I'm not happy in either household and I feel so alone and trapped. Im afraid to talk to anyone about this, as my  parents think there should be nothing wrong with me, and that it would be almost like an embarresment to them. I cant talk to my counselor at school because they are honestly the worst and anyone Ive ever talked to about their experience with them has been awful and has only created more problems. I know this isnt about periods or sex or stuff, but I just really need any advice because its honestly so hard to find a reason to live anymore...I dont want to die, I just want to be happy and be okay again like old times....
