You can stop. Just pour out the alcohol and stay on here till it's time to go to bed. After your sleep, you will be more rational. Drinking is not the answer to your problems--it may cause a temporary good feeling, but it enslaves you and brings on a whole host of other problems. Drinking only ultimately makes everything worse.
Plus you'll feel bitter guilt for having failed. Please dump it out! Stop before it turns into a runaway train!
