Admitting you have a problem and looking for help is the first type of recovery. If you already understand why you drink and your triggers then your on the right step to get your life back on track. Learning how to deal with your triggers and loneliness is something that you will have to practice. Most likely you will slip and drink many times and finding a recovery program that works for you will be something that you will need to do some research on. The succeed with all programs are very very low. Addiction is a are thing to go through so put in the time to find something that will really work for you. If you don't want to join a recovery program then you can always do it on your own or go to a counselor that deal with drug/alcohol abuse.
Most of the time when someone says that they drink because their bored or lonely have more issues that they are fighting. Finding someone will most likely not help your problem with drinking more likely. You even stay that you still drank when you did have a partner and they had issues with you when drinking.
Good luck and hope you keep coming back to SR.
