My anxiety is killing me

18 male btw

so I’ve been in my flat for 3 days but I’ve not talked to anyone yet, except for intro myself to one cause my mum made me (which was so awkward and it annoyed me to do it like that). I’m not even sure most of them know I exist. But my anxiety is really bad, honestly it was like this for years but now I don’t know anyone so I can’t ignore it.

I’ve been mostly in my room last 3 days, the biggest problem is I’m too scared to go to the kitchen most of the time so I haven’t eaten much since I moved in. I really don’t want anything to do with my flatmates I’m so scared if them. I just feel really certain that they won’t like me. I don’t get along with regular people which they all seem to be. I’m so hungry guys :(

I could join them in whatever they’re doing I know but I just don’t feel like it. I guess I don’t trust them or feel safe around them. this is really bad I don’t know what to do. I just dont want any attention or anything right now.
