For the sugar issue...Maybe you can find alternative satisfaction? Could you try herbal teas that taste good, in lieu of sodas? I was eating desserts all the time to get a boost, but I switched to hot tea at night, and gum or sugar free hard candy during the day. I ordered a big container of xylitol chiclet type gum off of amazon. It cost $14 and it took months for me to chew it all.

I’m sorry you are struggling emotionally/mentally right now.
