totfit is right - plenty of places to go that aren't beer gardens. No need to stay in unless you want to. For a real treat, take a walk tomorrow morning at a time when you would normally be pulling the covers over your head because the morning light was making the hangover worse. Lots of interesting sights, sounds, and smells in the morning. Some of them are freshly baked, too.
Change is possible. Hope is reasonable. You can do this.
