I think I’ve killed myself

I’ve been on a lot of meds for years but I think the doses have been increasing. I was getting dizzier and dizzier, but I tried not to say anything because I didn’t want them to stop my medication. I went to the mall last night with my friends and I was already very dizzy, but I had a few drinks and then I blacked out. I think I hit my head on something because when I woke up, I had a really bad headache and couldn’t remember what had happened. When I came to, I was sitting on the sidewalk. I was crying, and my friends were screaming and holding me. I got up and started to walk, but my friends said no and put me in a cab. I got home and went to bed. Now I can’t get out of bed because everything hurts. I don’t know if I’m dying, but I think I might be. I just want to go home and sleep and never wake up again.
