I'm antisocial at the best of times, so I'm not going to be of much help, but I didn't want you to think that we were all ignoring you! I see my mother once a week, my son twice a week, and my daughter once in a blue moon. Sometimes there's a neighbor to wave it. That's the sum total of my social life, and sometimes that's too many people! The best I can suggest is to find alternatives to traveling. It won't be easy, and you may always feel that sense of loss. Have you considered a blog about your past travels, watching TV shows about places you haven't been, reading travel guides, making scrapbooks focused on the trips you've taken? Have theme nights for dinner based on favorite locales and the food you ate there. Acquire pen-pals from the countries you liked best. I was very much an outdoorsy person and spent most of my life roaming through the woods. I can't do that any more, and I've never gotten over it, but I do find joy now in watching nature from my rural back porch. I bought decent binoculars and some bird books, and while I don't know the different between a wren and a sparrow, I do have fun looking for the bright birds or anything different. I took an online class about tree conservation and how to identify the ones around me. I've been reading up on the medicinal weeds that grow around my house. I may not be able to get into the woods any more, but I'm finding ways to bring it to me, and it really does help a lot.
