I'm sorry to hear that but tomorrow is a brand new day. Could I ask why you left the meeting after finding it was all about service work? Maybe helping others will help you help yourself and also get you out of the house.
I've done the whole sitting by myself for days on end drinking and it's a horrible place to be. It makes you feel like crap and that there is no escape when you know that there is, all you have to do is throw out the booze.
Therapy or maybe grief counselling would be a great idea if you are honest with them, it's a pointless exercise and waste of money if you aren't.
As Dee said, please don't mix your meds with alcohol that's so dangerous.
Take care.
