There's nothing you can do but MAKE yourself go out- I know it's not easy- I restarted the same behaviors and am going on a month of staying inside. !-!
Maybe its time to make new friends, maybe people here who live in the same area and understand your issues. Maybe find things in the paper you would look forward to? All else fails, you can have your boyfriend drag you out like mine does. (I'm kidding, don't do that)
Either way, there are many amazing things waiting outside, it's bad enough being prisoners in our own homes, but it's almost frightening to think we're our own jailers. You deserve to have the life of your dreams and I hope, with little steps, you can finally make it outside. ^-^
