AITA for thinking my mom is being emotionally neglective?

A little background info: I am young. I have had either no friends and/or fake friends all my life. Currently, I go to online school. I talk to my sister through discord because she lives somewhere else.

Recently, I have been clinically depressed, not feeling like doing anything, even some of the stuff I usually like. So today, I was late on multiple assignments. When I actually started doing some, I started talking to my mom, who was also doing stuff in the same room. "Y'know, keeping me from talking to M (My sister) is not helping with my life..." "Keeping you from M? Honey, you're keeping yourself from M" (She doesn't let me have the internet until I finish my work) "This is why I never tell you stuff, because instead of actually supporting me, you just enforce more of your shit on me" "Don't cuss." "If you really cared, you would be more focused on how I'm not doing well rather than me using the word shit" "And now you're being manipulative." I started just crying and went off to my room to cry further. Thankfully, my dog comforted me. This kinda stuff has happened for years: I try to talk to her about how shit my life is and how I'm feeling, and then she starts saying stuff like "So I just sit here and listen to you yell about how you hate me" when I start talking about how she doesn't even support me. I can't even tell her more than half of what my life is actually like and what I feel, because If I did, she'd only send me to yet another mental hospital. I'm afraid to tell her anything because I know she will only manipulate me further.

I don't know what to do. I haven't for years. I have no friends (except for my sister) and my mom is like this. Life is shit. I don't seem to have a way out and all I can really do is cry by myself. Please, I jus want some advice on what to do.
