If you could write a letter to yourself as you started uni, what would you say?
So, my friend, learn to be a no compromise follower of Jesus.
Ask Him outright if He is able to find friends for you. Don't just assume He will only give you loser, frumpy friends. Check out the Christian groups, don't just assume there won't be any "cool" people there.
Take a risk that way .....ask God to show who He is to you!
You are way too insecure, maybe even take a year out just to gain experience and grow up a bit.
