You need to DO
something about it and not just sit there with a clipboard, chalking up another one every time a so-called friend leaves.
There are lots and lots of people in your territory, and many of them are potential friends for YOU
On your clipboard instead of making marks for friends lost, devise a plan of how you can meet new safe friends. Clubs, organizations related to your interests, develop new interests. Take up clogging or square dancing or something. Become a plumber and take up unclogging.
Maybe you need to redefine who you are somewhat.
Become ACTIVE to remidy your situation.
