Alcohol in general (it doesnt have to be to the extreme of having alcoholism) affects many things including diagnosis. which is why most if not all mental disorders recognized in the USA carry the requirement that the problem is not because of alcohol or drugs....

let me give you an example... one beer for some people can cause a persons mood to change, can cause someone to feel numb, a bit spaced out, and a bit disconnected. the doctor now doesnt know which the person has ...a sensitivity to alcohol or any number of mental disorders or any number of medical problems...solution take alcohol out of the situation, have the person come back after they have not had any beer for so many days, and send the person to allergy testing and other medical and mental tests once the alcohol is no longer a factor. I know many teens and adults, that ended up getting diagnosed with all kinds of mental and medical problems simply because they had a beer with their friends.

just a bit of information here where I live your statement......

it just became all that I wanted to do. I get cravings and impulses to drink too, but that's more mental.

is considered being addicted / being an alcoholic\ having alcoholism... not saying you are, only your treatment providers can say this of you, just saying .....if you were here where I am.... thats what it would be called.

Sometimes teenagers (and some adults too) dont realize that being addicted to something doesnt have to be physical it can be physical or mental or both.

I understand it hun, I think. I have moments that seems like the real gets sucked out of reality. I feel disconnected, and objects seems to be fake.

I usually go "here we go again" and sit it out. It often happens when I'm hit with too much sensory stimuli, like walking into a busy grocery store with all the lights, colors, people. I just walk around in a daze till it fades away, or ground myself by picking up items and reading the labels.

It doesn't bother me anymore because it happens too often. The only times it does bother me is like when I'm driving going over a high bridge. The overhead girders produce a strobe affect which triggers it which triggers my anxiety because I'm going 70 mph which then leads to a panic attack which leads to depersonalizing which almost causes me to pass out. I have to cross the Mississippi bridge everyday sometimes. It's like 300 ft in the air and 1/4 mile long, usually by the end of it I'm a wreck, and it takes a mile to calm down, but the shock lasts hours.
