I am sad, it feels like I am loosing my friends, my friend is getting on my nerves,how can I make new friends?

Well I would say any friend like that isnt worth keeping? If she cant act the same when she is around u with friend then acts different thats not right.And it seems like she wouldnt be the best friend u can have. I would say still be friends ,but when making friend u can go up to them say something like hey or whatever ask them how are they doing. then just start talking to them in any cles u have with them. then maybe if u wanted to invite them to eat with u at lunch. i hope i helped u.
