Find new interests, rekindle old ones, just get out. Even if it's basket weaving, it'll be worth it for one night just to say you tried it. Who knows, maybe you'll like it, and maybe the people you meet doing it will be worth knowing. I know you're not into what you're finding on meetup, but I've gotta tell you, the board game nights have REALLY lifted my spirits.
Don't watch the U-Haul. I know it's a metaphor, but don't do it for real. No matter where you are mentally and emotionally, it'll hurt, and it isn't worth it.
Glad you're keeping the dog. The only creatures that love unconditionally are dogs and small children. Everyone should have a dog. Smelly, ridiculous beasts, but they make up for it.
