Bad night

Last night I had such a bad night I even considered getting medical/psychological help , well psychology is also medicine , right ?

I feel afraid at night many times , that's not new. But last night I felt so much fear.I was so scared.And I had all this thoughts, but not as normally , I don't know how to explain but i'll do my best...
It was like the thoughts were crowling up my head and my head was a room with 4 walls, and my thoughts were crowling up them at very high speed, while I felt fear and pain.

I remember thinking to myself really quickly:
I need help , I can't take it , I can't go on like this , it's obvious now that I need help.

I don't know if tell my dad what happened . I just don't want it to happen again , because I was terrified.That wasn't normal , there was something wrong with my head.

And It makes me scared , It makes me really scared.

But is weird telling my dad , and I'm sure he won't even take me seriously and will say that I am a fussy hipocondriac.

I don't know what to do.
