long distance relationship. advice pls

Afina
Anyone here been on long distance relationship before? Is it hard? How do you go about it?
I met this guy two months ago and I suddenly had to move country so now we are doing long distance relationship. Due to work and financial we probably will only get to see each other once every two months, and probably for only 4-5 days. 
Anyone has any advice on how to go about this? I'm excited to the countdown of seeing him but I'm also sad that it'll only be a few days before I have to wait a couple months again.
