I am sorry to hear you can't get away. I run my own business too so I understand all the stress and complications.
Are there free counselling services where you are? Is that something you can look into?
Believe me, I know what I am about to say is gratingly annoying and sounds patronising, it is not meant to be- but- if you stop spending money on alcohol you will have more money for something like therapy. I know, I know, easier said than done and it is the therapy that may be the thing that helps you stop drinking so you need to get in there first..... It is so tough, I get that.
You really sound like you would benefit from professional help though. Another option is AA meetings, which are free and if you are in a big city available almost any time of the day. Could you look into that?
Sending you hope and a hug.
