Meg...prayers your way.
Many of us have been there and are now reasonablly happy....you can be too.
As others have said....see a doctor....be honest with him/her.
Reach out to the good folks at AA....be honest with them as well.
You can/will be fine....Try not to worry too much about the job...if you don't stop the drinking, you probably won't have a job very long anyway....put your sobriety as number one today and things will work out. It's pretty amazing.
All the best.
