After some consideration I've come to the conclusion that I'm an alcoholic.
Is there something in particular that makes you think you're an alcoholic?
I say that because my family and friends always need me to stop drinking
It is not good to overindulge in drinking. It can quickly become a habit you will have to maintain and it can destroy all of your relationships.
I know.
It takes a lot of courage to admit you have a problem with alcohol. It can be a very serious issue and I hope you can get help professionally via a counselor, group therapy, etc. You deserve to be happy and well.
