I want the old me back! Help!

Hi everyone. I'm a mum of 2 fantastic but exhausting boys. Happily married to a loving husband but I've lost myself over the years. I'm heading swiftly towards middle age and not liking the way I look or feel one little bit.

We are the typical "sandwich generation" family stuck between commitments to our children and the increasing demands of elderly sick parents. I'm a lifelong emotional eater who's trying desperately to break the habit. Stress is my major trigger and we've had a huge amount of stress in the family over the last few years. My weight has reached critical point. I've finally accepted that for everyone's sake (and not just my own) I need to put myself first for a change and focus on getting myself healthy. Would really appreciate any help or advice out there.
