I can really understand how you feel, lots of my family have it. Have you let your housemates know? If they understood what it is and why you may find it harder at times they find easier it might help. It really helps to let it out and tell people how youre feeling. I think you've done really well getting into uni and making the effort to be sociable, so keep it up, it will gradually get easier. Have a few questions/ topics lined upo to talk about with people, then theres not so much pressure on thinking things to say. I also suggest getting onto amazon and buying a couple of books. 1. Overcoming social anxiety and shyness. 2. How to talk to anyone. These have good techniques on how people think, what to dom in those awkward silences, changing how you think to make socail situations easier because i think it would help if you had a few 'rules' to follow, a way of doing things so you feel more in control. Could you speak to your family? I dont knoiw what your situation is but it would be good to let them know.
