a week after binge drinking feeling horrible

A week ago today I started a weekend of very heavy drinking. My Son goes to his dads house every other weekend, so I decided to have one weekend full of fun for myself. Friday night I went out with some friends and drank a lot of beers, a couple mix drinks and a shot. I got really really drunk and actually fell asleep in my friends car on the way home. I woke up Saturday a little hung over, but still feeling like my normal self. Saturday was the night that ruined it all. I went to a friends house for a party and drank a verrry large amount of rum got sick and passed out on the couch. I woke up Sunday and something was very different. I picked up my son with my boyfriend and went home. Thank God my bf was there because I felt horrible, completely out of it, I could barely make sentences, and had a couple waves of paralyzing panic attacks. I thought maybe all I needed was a good nights sleep and then I'd wake up Monday feeling back to normal, but this was not the case. For seven days now I haven't been myself. I can't focus, I can't do normal tasks, I've noticed my vision is worse than normal, and I just feel all around stupid. I finally went to the doctor today and they did blood work and an ekg only to tell me that I was healthy and to keep drinking plenty of water. I honestly feel like there is something wrong with my brain and I am terrified. I feel like I ruined my whole life in one night and that I'm never going to be my normal self again. I'm heart broken because my son means everything to me and I need to be 100% there to raise him properly. I've already made the promise to myself that I am NEVER drinking again. I feel so hopeless and have such a horrible feeling that this will never go away :(. Is there anyone out there that has experienced anything like this? Did you ever get back to normal? I would really appreciate some input on my situation because honestly I am terrified and in tears right now.
