<human>: I'm 20/F and have been in my very first relationship for about 6 months now. My SO is 23/M. It's been a really great start and I like to think I'm doing pretty well even with my lack of experience, but there are times that I start doubting myself and end up over analyzing situations as simple as eating across from him at a table in a restaurant. I'll start to feel awkward, then I begin to wonder if he is feeling the same, so maybe that's what is making me feel that way to begin with, yadda yadda yadda. It all builds up and my brain doesn't seem to want to TURN OFF.

I'd really appreciate some input on how I may be able to control this and start training my brain to be a little more "in the moment". I'm still learning a lot about what I want and don't want, and I know I definitely don't want this to become a bad habit for me!

Give me the gist of the text in a nutshell
<bot>: First relationship ever. Have an issue of over-analyzing situations when I'm with my SO. How can I teach myself to stop?
