Is my mom verbally abusive ?

She knows I have depression and anxiety and she still says things like this to me all the time when she’s upset she will throw chairs and break things when she’s really mad

and because of what I’ve been through it really gets to me I’ve explained several times it’s not fair and croses my emotional boundaries and she continues to say things like this anyways and it triggers me and makes me feel bad like I’ve failed as a daughter I do family therapy and have put a lot of effort in but I’m seeming to be the only one improving my moms excuse for not getting help is “ I don’t have insurance” many times I’ve told her she needs mental help I’ve tried to be understanding of all the things and stress she has on her plate taking care of my grandpa who has cancer and being away from home but I’m a child why do I have to be the bigger person and always see two perspectives I’m 17 so only one more year but I can’t take this much longer
