I Dont Know Who I Am Anymore

My dad was always the drinker. Anything that happened warranted a drink. But he's been locked up for a year now, and I've noticed that my drinking is growing. I've never been legitimately, not all the way here, drunk. And I've never made myself sick. But I just downed enough, fast enough, that I covered my bathroom in vomit. I cleaned it and immediately started realizing what a disappointment I am. I don't what I'm doing. I don't know why I'm doing. I don't even recognize the girl in the mirror. I don't know who I am anymore".
