OrdinaryBoy, I had severe anxiety as well. I thought drinking calmed me down and now I realize it was the booze making me anxious. I'm still a little anxious, I won't lie about that, but it is starting to ease up a little. See how you feel after a few days and I bet it will be better. If not, I'm sure your doctor can give you something to relieve the anxiety.
At your age, it's never too late to still realize your dreams. You sound very wise for 27. I wish I had had your insight at that age. Please treat yourself with love and patience. Reward yourself regularly. Just try to stay busy. Drink lots of water. You may want to take a herbal medicine called Milk Thistle, it is supposed to help heal the liver.
I wish you luck young man. I know you can do this....
