Am I alone in this war?

I need to know that I am not the only person going through a spiritual warfare. I at all times of the day have very real evil spirits constantly watching me. Just waiting for me to mess up. They talk to me and at times I see their faces. HORRIBLE faces. I have had so many sleepless nights. They seem to be more active at night. Even at this very moment, they make me to feel crazy for even believeing that such things are happening to me. The only time that I get any peace is when I am at church. There are so many of them, I can feel them watching over my shoulder. I am at home alone most of the day. Things fall, I see dark figures out of the corner of my eye, I hear whispering. Am I going crazy? Please if there is someone else out there going through anything similar let me know. I need to know that I am not alone. Please Pray for me.
