Having had a broken heart more than once, I think the answer there is you move on, and eventually you find someone else.
As to how you empower yourself - if you feel you can;t stop drinking by yourself what about chasing up one of the recovery groups like AA or SMART etc....you could also find an addictions counsellor...failing that, rehab?
The important factor is change. Change what you're doing, leave the booze behind you and you'll find the power east - truly.
