Hi thecatalanperson. Sorry to hear you are feeling awkward about relationships. I am not sure if you feel okay about this person but it sounds like you had a new first time together.
Other lifestyle changes that help me are doing yoga, exercises, mindfulness, calm music, and being active on Psych Central.
Some people find the forums give them the compassion and empathy they seek.
