i need help overcoming paranoia

I need help overcoming my jealousy and paranoia

Each step that somebody i love took,I will definitely have heavy jealousy blooming inside my heart. I always thought that she will definitely fall for somebody else.I always thought that if she was with another guy,even some random colleague,it will always be she was 'with' 'somebody else'.. hahah..damn jealousy..always got me into heavy heartache..i hate that feeling..

I also have this paranoia that when people are talking behind my back,they are talking about me.about my bad things..I hate that part of me as well.I always have to keep cheating my brain to think that what they are talking is about something else.It makes me feel like I'm hated by everybody else.That sort of feelings is not good for your health you know.

I wish that I can overcome those feelings.
