Thank you for your kind words and info Arabesque!
I used food as an instant mood stabilizer and it used to give me great joy, even temporarily. As you said that has stopped now in a very radical way. I haven't seen a therapist pre op about my food issues but now I feel that I really need it. Started searching today but the one I was referred to is completely full and doesn't accept new patients at the moment. I'll keep searching for a therapist and I am sure I will find the right for me. I also have a call planned with my surgeon where I can ask him about all these worries that are bothering me.
I will surely stop taking seriously opinions and comments on FB groups, I learned my lesson now. They got me panicking.
All the best to you too!
