Did my drinking affect my mood?

Im not an alcoholic. Well, I don t think I am. And If I was, it s a beginning stage and I m able to stop. I have stopped. I still like drinking though lol. But I was just stupid for a bit. Anyway, story is, I ve always been really chill. I was able to talk to people well. And I didn t really care about anything. But in a good way. I was motivated. But then I had to leave for the weekend and I stopped taking my antidepressants for those 3 days. And I drank each of those 3 nights because I thought why not? Then when I came back home, I started having about 3-4 shots a night and just listening o music. This weekend, I m really uptight and pissed off easily. I m stuttering just a bit sometimes too. I m 17. You think the alcohol affected anything? I couldn t have lost a lot of brain cells either could I? Sorry if these are stupid questions. Just kinda worried about this and I wrote this in a hurry. Thanks!
