As stated in the title, I have been recently trying out different personalities in my interactions with friends and family. For example sometimes I'm confident and charming; sometimes stoic and intelligent; sometimes funny and energetic; sometimes cool and relaxed. I am wondering how you determine which personality is the best fit for yourself and whether I should stick to this 100% or continue to experiment with different styles?

Also, I was recently diagnosed with a general anxiety disorder and have lost a lot of friends due to not fear of public spaces, fear of being judged, overthinking simple things, etc and withdrew from university last fall. I used to be very popular and successful at my university, but once I dropped out of my fraternity and stopped hanging out with the friends made due to their drug usages, I pretty much lost my core group of friends. In spite of this, I still see them everywhere on campus and they are pretty much unavoidable. Now I feel that my reputation has been damaged and now they see me as lame. I am wondering how to make new friends who don't do drugs and how I can get back to the grind once I return to university this Spring. For context I am 6', 178 lbs, and 9% bf. I have read most of the posts on here and I realize this is mostly about sexual strategy, but my struggles pertain mostly to finding a new friend group that will help me succeed as I have been a lone wolf the past 2 years. I appreciate all comments. Thank you.
