I drank exactly like you and thought like you did. That was a few years ago. It got progressively worse. I quit a little over a month ago and even when I quit, I wrestled with the same questions. I had mild physical withdrawal symptoms when I quit. It was not until a few weeks ago when I was sober enough to reflect and see how bad I was. I never want to go back.
My only advice is give sobriety a chance for a few months and if you feel you were better off when you were drinking then go back to that. I think its too soon to make that call and it may be your brain playing tricks on you in which case yes you prob do have a problem.
