From what I can see is that you are making too much judgment towards yourself. You need to realize that you are you.

Do some self awareness tests on yourself like write out what you like and don't like, your interests and what you want to find in a healthy friendship. Looking into "Assertiveness" helps too.

I think you are just over-thinking on yourself which is creating anxiety.

I also want to put is everybody has those moments time to time where they will feel out of place from others.
