Welcome to the forums,
The best person to tell you that you have a problem is yourself. Once you have admitted that you have a problem you can begin to solve it. You'll find that not many people will come out and tell you that you're an alcoholic, even if they know you are. Acceptance is the key to success. You can't really make any positive steps if you're shrouded in denial. Unfortunately denial is a pretty prominent aspect in alcoholism and addiction. I hope you find whatever it is you're looking for and start the journey of recovery.
Natom.
