Hello Krayav,
I don't know if what I'm going to write down here will help you much, but I hope it does if even just a little.
I'm sorry to hear about your move, and that everything you knew had to be left behind. Judging by what you wrote, I can only assume this is your first move, or at least the first after staying in one spot for a long time?
Eitherway, I don't know much of my family either. For various reasons. I have, however, in the last year to one-and-a-half started to get more in touch with a certain part of the family. However, they don't seem to contact me often... Eh. I don't feel I am missing much though, but that's just the way I grew up, I suppose.
We constantly moved, and one friend I recall leaving behind... still to this day I sometimes feel... and think I want to meet her again, even if it's just to properly say goodbye and to thank her for the time we had together, but... I have nothing to go on. And as far as I am concerned, she might be studying on the other side of the world or whatnot! I don't know.
In a way I can relate and can't. I don't know how to help, but... if you ever want or need someone to talk to, feel free to PM me
Take care *offers a hug*
