my anxiety rises to unnatural levels whenever I think about approaching someone at uni

Just moved into another city to start attending university. Today I am completing my second week of uni, and during these 2 weeks I’ve realized something. That my anxiety is crippling and that my self esteem has hit rock bottom. Everytime I even think about approaching someone I get so nervous an anxious, my stomach starts hurting and my palms start to sweat. I can’t open my mouth to say a word, and my mind is an endless montage of hoe everything could go wrong.

I don’t wanna approach someone and say something that makes me look weird, and I especially don’t wanna approach 2 people who seem like they are friends and already in a conversation. I don’t wanna be that annoying outsider that doesn’t leave you and your bestie alone, which constructs you of talking about specific issues and things with them. And most people already created friendgroups, and I’d feel weird to just go and insert myself into said friendgroups. I don’t wanna be that entitled and annoying person who inserts themselves into everything and don’t leave you and your group alone.

Anyways, that is all I’ve got to say. Any advice on how to stop being a blubbering mess and how to find the courage to act and socialize as an actual human being would help lots.
