I think I drink too much and it's gotten out of hand.
Why has your drinking gotten out of hand?
Alcohol makes me a different person. It happened a few times so my family is upset with me because of it.
While drinking in a responsible manner is fine, it is bad to lose control and drink too much regularly. Perhaps you should sit down with your family and apologize for your behavior and get some help to stop drinking so much.
I guess I should really do that.
Once they realize that you have realized your problem, it will get better. Too much alcohol can ruin lives.
