I just wanted to welcome you and say that I know that exercise increases endorphins and boosts your mood. Just be careful with going off of your meds (I'm no doctor). As for the "bad fork in the road" I always say to people what my coach used to say to me, "noithing hurt, let's get 'em next time!" Which simply means, just get back on track. You now know that journaling helps and when you don't journal, you get off track. Plus, you've inspired someone to get healthy with you, which is always a good thing.
The past is over, now let's get it!
