Perfectly said @The Greater Fool.
Using food to numb ourselves from emotional pain, depression, anxiety, stress, etc. is very common especially with people here. It’s the same as those who use drugs & alcohol to mask their pain & become addicted. Eating, regardless of how much is consumed, never stops the pain because it’s still there. So yes, you are experiencing withdrawals & grieving your inability to eat the same volume of food & food choices. Seeking support to understand & learn how manage the emotional or mental pain will be helpful.
All because you can’t have your whisky now doesn’t mean you can’t enjoy a glass in the future. As long as you’re aware of addiction transfer & your greater susceptibility to it, having a glass on a Saturday night will be okay again.
Congratulations on your weight loss so far & the life you are regaining. So much to celebrate & be joyful about.
