It's possible that when you lost the comfort of therapy, you turned to food for comfort.
I gained about 40lb since I started therapy, and that was comfort eating due to everything I was going through. I have lost 14lb in the last month, and I think it's because I am personally in a better place (still in therapy). If you (like me) have patterns of comfort eating, it can be changed with self-awareness and determination but it is hard work, so do be kind and patient with yourself.
