It's been a pretty rough 12 months MD, if you came out on top of the clouds brimming self esteem then i would think that perhaps there was a problem.
You've had a lot to deal with and it's probably taking its toll. Let me assure you, that although you feel like you have taken a beating with the ugly stick, no body else thinks that.
You'll love yourself soon enough again, but i think it will take time.
