Hi, I'm A 19 Year Old Guy And I've Been

Hi, I'm a 19 year old guy and I've been having lots of difficulty sleeping lately. I've always been having trouble sleeping but since I broke up with my girlfriend I've been having constant nightmares about her and her new boyfriend. I thought they would just go away as time went on but it's almost been a month now and there hasn't been a single night that has gone by where I didn't have one, and they keep me from being able to sleep. As well, this last week I've been have wet dreams along with them. I had bladder issues when I was a kid but I thought I was long past that and they won't stop. What should I do?
