Social Interaction Advice???? 😰

HIHIII! Okay so just for context, I've had/am currently in (kinda?) a low-key really toxic irl friend group- but for around a month I've been distancing myself away from them as much as I could, however, since I sat next to them in a few of my classes I had to go through the whole process of changing seats and stuff like that. LUCKILY- I could do so easily, but now I need different friends to talk to at lunch since my old friend group always tried to find me. I genuinely suck at social interaction IRl, and I get really awkward/scared whenever I try to talk to people so any advice to find friends would be appreciated 😭
