I really hate going to bed at night, any advice?

I really fight sleep and avoid going to bed, yet I seem to need so much sleep. I also used to like living alone and being in bed alone, now I hate it. I feel lonely and scared? Almost. When I think of closing up the apartment and switching off the lights I get a hollow empty lost feeling inside me. So instead I stay awake all night. If I take sleeping pills I fight them so that I don’t have to get into bed. Any insights? Or tips would be appreciated.
