Hi buddy,
Well I know how it feels when your best friends get busy with their own lives and move far off away from you. But living in that zone for the rest of your life is not the solution. You may not get friends like them again who are always there for you but you can atleast try and make friends with people who understand you. Unless you put behind your shyness and the ideology of ideal friends you won't feel anyone can be your friend. Just for once try to forget everything and look at the world with hopeful eyes. You surely will get friends.
