Need major help, I think I'm bipolar...

So, I've been in a relationship for about 2 months now and I notice I get mad at the littlest things. But I can't help it. Like I'll get mad if he is having a talk with his mom for 2 hours, cause he's not giving me ALL of his attention. I have MAJOR jealousy issues and trust issues from men in my past, and he's done absolutely nothing to make me feel this way, but I can't stop and I'm afraid he's eventually gonna leave me because of how insane I am. Someone tell me some was I can stop being so jealous and so impatient and selfish all the time please I need it. Also, please don't leave rude comments, I'm upset enough without them. I just want to stop being so mad at him 24/7 it feels like, I'm shocked he hasn't given up yet because of how I act.
