Am i crazy??

Ive had troubles sleeping since i was 5, ive had some traumatic situations happen to me but not enough to remember. Ive never been seen by a doctor or psychologist but i have horrible vivid nightmares each night sometimes im afraid to leave my room because i start seeing things when im awake, the nightmares have toned down since ive been with my boyfriend but recently ive had a really bad episode. Should i see a doctor? (Please dont judge)
