I was seeing a girl for a couple of months or less and things were going well. I was living in the moment, having fun, and we were both really enjoying each others company. I met her friends one night and started to feel all sorts of anxiety and uncertainty about the relationship. I started getting pretty into my head that she wasn't into me because of my social anxiety. The following weeks I was overthinking everything and overanalyzing everything even though everything was in reality fine. I think she picked up and this and wanted to end things but came back around after we talked. When I last saw her I was so anxious I was going to be rejected again and had so many physical symptoms that I essentially bailed at the end of the night and didn't communicate how I was feeling well at all. 

I tried to communicate how I was feeling the next few days over text it all came out wrong and she said wanted to go separate ways. Haven't seen her for about one month now and she doesn't want to talk. 

I feel pretty jaded from this experience. I really like having relationships with new people and really hate that I didn't just let her in on how I was feeling or be more communicative. 

Any advice or help to put things in a different perspective would be massively appreciated. 

tldr: anxiety and not communicating kinda ruined a relationship
