I may have a fear of being alone...?!

I may have a fear of being alone...?

Hmm...not really panicking about the fear itself. But when I'm the only one upstairs, or in the house...I start to panic and sweat. And it's not just alone physically. I fear of never having somebody there for me. *lonely* So...is this normal for anybody? Because sometimes I get so afraid of being alone, that I think of the worst case scenarios that could happen to me. I'll end up locking myself in my room until somebody gets home. And even then I'm afraid that somebody will bust through the door at any given moment with a chainsaw. And I haven't even seen that movie! It has caused me to become afraid of the dark, and what's in it. How do I cure this? Is it normal for this to happen? I know what's happening to me, but is there a name for this? Just...tell me what I need to know.

Thanks in advance.

but I didn't go to any therapist or doctor. I just think of a happy moment and think that God is always with me. dats all.
