I had Wes when I was 19. It was rough but I grew up instantly. I wasn't on any meds then and was actually more stable. I am getting worse with age. LOL.
IF she ends up preggers, then worry. The meds are scary, but the docs will be able to guide the both of you towards the best decision.
I hope this isn't the case. Just hang in there. Try to occupy your time with other things. (I hate waiting for anything, let alone waiting to see if your life is going to change dramatically.
