fridge adding my well done! I wonder if you will find that the eating and drinking emotions have some overlap and it might give you a lovely community of people that make you feel stronger and that can only be a great thing. Because as lovely as pizza is it is never as good as feeling welcome and in a hug of support
Grey I agree with the above. My parents split up when we were teens and then handled it TERRIBLY but I am so very glad they did! They were not great together and are much happier now. You cannot live your life in misery to make the kids happy when, in fact, they may already not be getting great vibes. Either way I would do what you need to do for YOU. It is not being selfish, it is trying to make everyone happier in the long run and you will all be ok.
It may be partly that if you are re-evaluating things from a personal care point of view that this has brought the issue forward because you can't ignore it any more. You can't make your body a temple and ignore your soul in there. It is worth giving yourself some time though of adjustment- 6 months sounds good and then you can work out how you feel once the weight loss is sort of under control and you have thought about what next. But if it helps (it makes me cry) there is a great piece by Cheryl Strayed which I think sums it up:
Go, even though you love him.
Go, even though he is kind and faithful and dear to you.
Go, even though he's your best friend and you're his.
Go, even though you can't imagine your life without him.
Go, even though he adores you and your leaving will devastate him.
Go, even though your friends will be disappointed or surprised or pissed off or all three.
Go, even though you once said you would stay.
Go, even though you're afraid of being alone.
Go, even though you're sure no one will ever love you as well as he does.
Go, even though there is nowhere to go.
Go, even though you don't know exactly why you can't stay.
Go, because you want to.
Because wanting to leave is enough
Good luck and be kind to yourself
