Angeleah, I feel your pain. I'm on my last series of Depo shots which I believe is stalling my weight loss (I lost 6 pounds in the first week and not much else since). Exercise may give your metabolism the kick in the *** that it needs. Walking is great, but try to add a little resistance exercise too (weights... but bike riding counts for the large muscle group). While I'm losing at a snail's pace (1/2 pound every 2-3 weeks), the exercise helps keep the stress down and I sleep better (both play a part in keeping me motivated). Plus, I'm accomplishing something (okay, it's not climbing Mt. Everest, but it may as well be)... my committment to a healthier me.
