Every time I hangout with him, the second it's over I feel like I'll never see him again and he doesn't really like me. I am so aware that the thought is irrational but I can't get rid of the terrible feeling it causes.  I don't understand how I can be aware that a thought is irrational but still let it upset me.   Maybe my brain is trying to tell me that it's not an irrational thought and I am right to feel the way I do.
