do i have it?

I am very possesive of my friends and if they go away and talk to other people I get paranoid about what they are saying behind my back. It sometimes gets to a stage where I have to be on the phone or talking to them because I am paranoid how they are pecieving me, I feel a way to keep them for talking about me or thinking of me in a abad way is if I speak to them always

Please help, this is taking over
