Anxiety and uni

I’ve had social anxiety for a while (from about 14, potentially exacerbated by parent death or puberty, I’m now 23) but I was able to mask it slightly, I’ve realised my anxiety is not getting any better and seemingly worse. I leave the house only for work and compulsory university sessions. I always have to give myself a pep talk when going somewhere. Doctors have recommended talking therapies but that sounds daunting as it’s social, plus I keep cancelling dr appointments. I don’t have friends anymore as I do not spend quality time outside due to weird anxiousness. I also can’t do phone calls. I’ll see people that I made friends with when I was calmer and i become so uncomfortably awkward and feel like crying and shaken, especially when new people come along/crowds or groups. The worst is seeing people feel my anxiousness when greeting me. It’s currently exam season and I’ve been crying on and off, not sleeping, shakey, scared and avoiding my friends. How do I help this? I have pcos which I worsened by sedentary lifestyle due to not going outside/gym anxiety. I also have IBS which I think anxiety developed. It’s consuming me.
