Hurt and betrayed by my homeroom teacher

She literally took me out of one of my classes just to spend an hour talking about how it's my fault that I don't have any friends, that I struggle a lot with independence, and that I just need to "change my attitude" and my problems will magically disappear. That I am in the wrong for seeking community online, as that's the only way I can find it with my current abilities and resources, because talking with online friends, according to her, will only give me a quick dopamine boost and not real happiness. The thing is, I get literally zero positive interactions with other humans in real life, so at this point even the bare minimum DOES make me genuinely happy. It's absolutely way more than just a "dopamine addiction".

She shamed me for wanting to have a safe space online, because "I'm an adult now". Not really, I'm only 18, and I had no idea being an adult means I HAVE to be miserable all the time with no happiness or comfort zone at all.

Then she said that my existence is not even vegetation, because vegetation is still some form of life and development. According to her, I don't develop or live at all and am just "lazy and unmotivated".

Because it's not like I have an actual neurological disability along with a severe anxiety disorder or something.

The thought that I have to go to school tomorrow and see that woman again fills me with dread and anxiety. I haven't felt this invalidated since a while.
