Hi Katie,
I think maybe you should do as much research on this new city as possible. Find places that are going to be near you (stores etc)& maybe you can look for a support group in that area that deals with anxiety.
Will you be working or going to school, where you can meet new people?
If not, maybe classes at the gym would be good for you to just meet some locals. Also, volunteer work can be really good too.
These are just a few thoughts. I have had to think about the same things since my husbands job might be moving us 4 hours from my home town & all my family in November. I know I'll be ok with my husband & kids but it is such a lonely feeling to think about him going to work, the kids going to school, & me there by myself ALL day not knowing anybody. I stay home so I know my kids & husband will meet new people but I will have to find things to do to keep myself occupied.
Maybe I'll even go back to work.. who knows.?
Anyway I hope all goes well!
Chanda
