How can I (as an adult) overcome my fear of the dark and other things?

I have many fears such as heights , feeling trapped as I have a disability, were I have no strength in my arms and hands. I panic when I cant lift my self out of places. but most of all Iam terrified of the dark, I have always been scared of the dark, because I have had paranormal experiences in the dark and the day time i feel as though i am being watched / followed in my experiences, I have had spirits touch me and throw things at me and stand there and watch me and even say stuff to me. I need help please xxx
