I'm an alcoholic and don't know what to do.
Are you being serious? Why do you think you're an alcoholic?
Because I spend a lot of money and time on alcohol and feel bad about myself afterward. I just want to drink.
Now that you are aware that you have a problem with alcohol you can start doing something about it. It would be wise to seek treatment for your addiction, you don't have to go through this alone.
I need a drink.
I think you should seek professional help instead. Alcoholism is very hard to kick on your own, most people often need help.
