Yes, you APPEARED weak and stupid. But you're not.
You made a mistake, a very understandable, common mistake. Don't do it again. You've been through the weepy first week of groveling and begging. Don't slip back into it or you'll spend more time recovering.
I'm not a big fan of using alcohol to solve your problems, but I've found ONE beer an hour before I plan on going to bed to be helpful.
