I find stressful situations HOOK me the next thing you know my mind is like a whirlwind and i'm thinking all sorts of crazy stupid stuff. Now these days it wont lead me to the bottle I dont think. But it will drag me to the pit if i'm not careful. someitmes days and days can go by before i get ahold of myself as most stressful situations sometimes can go on for days weeks months etc..
The trick is to not get hooked and if you get hooked to quickly recognize your hooked and find a way out. For me exercise will help or shifting gears reading a book distracting myself with something else etc...
