The best way for me to stay posititve is by first writing down all of my negative thoughts, then I go over it, as if I"m having a conversation with myself and reply to the negative with positive comments, just like what I'd tell a friend. I keep doing that and sometimes I'll forget about my anxiety. I also envision my dreams and what I'd like to do. This used to be hard for me during a period of my panic disorder, because things were so hard for me to believe... I didn't want to be disappointed if my dreams never came true... but lately, I feel that I'm enjoying just the moment that I dream, and whether it comes true or not, is not the main point.
