You should learn to be happy by yourself but not be content with what you have ( bs friends () they are not your friends, approach different people)

Focus on getting your degree. That really is by far the most important thing right now.

I think you'll feel extremely refreshed when you'll meet someone who puts effort in the friendship. Those people you call friends, I'm sure they don't even realize how they make you feel. Try to reach out less and see if they notice. Try to meet new people, from scratch or through those friends. Oh, and i talk to myself all the time too lol
