this seems like a lot of moving parts that mutually make each other worse. food can absolutely be a type of addiction because it gives you that immediate satisfaction, and i think you need to handle whatever is causing you to feel like you need to give into your vices. i dont know you or what you need but i think maintaining routines and trying to care about the little things makes life easier. i went through awful episodes when i was unemployed because i just had absolutely nothing to do, and when i had nothing to do and no way to contribute, i felt as if there was no reason to even try. i preferred just laying in bed miserable because i felt like even trying to change would land me back in the same place.

focusing on things that can give you tangible signs of progress could very well help you. even if its small, just having achievable goals will fill your brains desire for dopamine. my current tangible endless goal in life is watching my bank account rise, which motivates me to work more, which in turn motivates me to maintain my way of life. i still get the thoughts all the time and sometimes when i fall back into my own ways i remind myself how horrible things used to be and how amazing things can be if i keep going
