It's expensive but invaluable. If you have spent your life leaning on something that very soon won't be there, it can send the rest of your life into turmoil. A high percentage of relationships can be affected by it. I hear people say all the time 'I am not worried about my marriage' but I think that is naive. A lot of us have been addicts with food and just like other addictions we use food as a crutch and a soother... if we rely on something then, and have done for a long time, how do we know who we are without it? How do our partners or friends know who we are?
I'd rather be unnecessarily worried about my relationships and pre-empt any upheaval.. learn to recognise it for what it is when it arises... than to not worry and be surprised when shit falls apart.
I have been to see a bariatric psychologist and can actually share the points you need to think about if you like.... it'll save you some cash haha
