Well as to why someone can move and seemingly not care, it could be a sense of adventure, or [like myself] they may be miserable in their current location. I do kind of know where you’re coming from, my family moved from my home town 15 years ago and I still miss it. Plus most of my friends moved away years ago so I don’t get to see them nearly as often as I would like.

It’s hard, but first you need to get comfortable being alone. Perhaps, if possible, you might consider adopting a pet. Doesn’t have to be a dog or cat. I’ve had many different types of pets, they can really lift your spirits. Try picking up a hobby. Think about stuff you liked growing up. [Think of all the adult colouring books!] While you shouldn’t rely on stuff to make you happy, perhaps you could collect things you like. [But don’t go too crazy or you’ll end up like me and suddenly realize you own 300 bookmarks lol] figuring out a hobby can also help you in the friends department thanks to forums like TinyBuddha.

I say this a lot but journaling and meditation can be a big help. You need to get in touch with your inner self and become your own best friend. It’s not easy or quick but it’s worth it.

Good luck to you.
