Sorry you find yourself here surprise. Nothing about this situation we have found ourselves in is fair.
Seek legal advice about your rights regarding the kids etc.
I too used alcohol as a coping mechanism, its not a good one. I used it during the relationship to quiet my screaming gut. After Dday I stopped as it doesn't help and is only an ineffective bandaid. The only way through this is through it - there are no shortcuts.
Take care of yourself, try to eat and keep hydrated with non-alcoholic beverages. Focus on doing what is healthy for you and your kids.
Me: Awesome - 35
