Bridgie,
From what you explain here, this guy seems to be good and positive. You seem to like each other, have a second date coming. Try to look at the situation as a positive one, it sounds great. You have someone who is interested in getting to know you. Talk with a friend if you are stressing. Its in my opinion not a good idea to talk about mental health issues unless both of you have it in common, or you feel he would understand. I wish you all the best, and happiness
