Try getting a hobby. go for a walk, go buy a new shirt, do your laundry. Join a club at your university/school, or maybe join an association in your community. What do you enjoy doing? Do it!
Meh. I havent made in a new friend in like 2 years. It sucks.
But when im doing something i love, then i feel better about myself and therefore am in a better head space to meet new people without feeling too self-concious and nervous.
take care
