My parents had a not so great marriage. Dad was screwed over at work, not so good relatives, mom did her own thing. I suffered a lot between pointlessly.
I am a very calm guy IRL, I have done many stressful jobs and never really felt anxiety, but my parents have this ability to say just the right thing to trigger extreme stress and anxiety. No matter how far I go in life, I can never escape that I can escape.
I made food my coping mechanism. Learnt to cook (when there were fights at home, id cook for everyone). I still eat out without my phone, sometimes without girlfriend or friends. So I can eat away my feelings, process my thoughts etc.
