Try not to worry, this is very normal (even if other people won't admit it). Two months isn't very long so it's normaly you would be missing him.
Give it at least six months and I'm sure you will no longer worry about him. In the meantime, do things you really enjoy!! Spend time with family and friends, go horse riding, play with your pets, bake cookies... anything you enjoy :)
