Tips on how to stop mindless eating?

I was (Still am sometimes) a compulsive emotional eater. I have an anxiety disorder and don't like being out in public and the first thing I turn to is munching on something to take my mind off it. If I could just 'not do it' I would, but I haven't figured that out yet. So what I do at work is keep a huge bag of baby carrots on my desk, I can munch on these all day. If I can eat 15 oz of baby carrots, go for it. I don't really like them though, which is kind of important. I also keep things like fresh baby tomatoes (the bitterness makes me not want to eat them) and those are my only two choices. At home is definitely harder since I pass all these lovely little restaurants on the way home. It's pretty normal for me to leave my debit card at home so I don't go out. Once I'm home and I think about the cold I don't really want to leave again.

Learning to not do it is very important, but I had to start by tricking myself. Lol.
