i get like that too, ive moved with a new baby and fiance, and dont know a soul. but it does help having the baby at times to move my ass outta bed every morning lol. i get the fear of going to the grocery store a lot lately. i do believe its anxiety because you are feeling alone, and perhaps singled out, for being a stranger person in a new place. you'll have good days and bad days, but never say to yourself theres no reason to get out of bed in the morning, theres always a reason even if is just to do a pile of laundry, or go for a walk, i find exercise really gets rid of my anxiety a great deal. infact one thing that really spurs me along is one walk in the neighborhood a day. you go by other people on the street, and see your not alone, other people are doin things by themselves too. its a ll about challenging yourself, face your fears smoothly, go to the post office more often if our scared of it, and strike u a conversation with the clerk so that you see them face to face and dont wonder what they think, dont live inside your head there is nobody in there but you, and that is lonley and depressing. we only really get an impression of ourselves if we continue to get feedback from other people. if you had moved there completely solo i bet you would have met more people by now, bc you would have pushed yourself, i think sometimes when we are with someone we forget the importance of being social.
to start join a club, anyone be it dancing or books or whatever. dont think theres something wrong with you because this tends to lend to the problem, what your feeling is normal, and wil get easier, probably already has, i could have wrote ur message a month ago!
goodluck
