I am suffering from anytype of paranoia?!

I am suffering from anytype of paranoia?

i've asked something before, and somebody told me i might be possibly paranoid,clinically.i think this as true sometimes. i dunno exactly. maybe you can help me out?

i actually have a few questions.

1. ever since i was little, i've been nervous, scared and everything. i know i have anxiety/ocd, and stuff. and im going to get myself checked out for that. but ive yet to learn what really i am. ok so, other than anxiety, i know ppl. can be paranoid with many types of paranoia. maybe one of those ppl is me?
i NEVER feel alone. no matter what situation, even if i AM alone, i dont feel alone. since i was young me and my friend were always into supernatural junk, ghost hunting.etc.
could that have triggered the paranoia?
i constanly look over my shoulder for no reason. and other than ocd/anxiety related stuff like checking things over over again, im gettin a bit worried. i cant even walk up my own stairs alone/w/ someone without looking over my shoulder and sometimes i get so scared

(continued) i get so scared, sometimes i almost feel like crying and i freeze up and cant move, just because i dont feel safe, in my own house. when im somewhere,ill freak out. i hate the dark. i like it sometimes, but then again i dont feel safe day or night. even the slighestt tick or creak or noise makes me think somebody is watching me.
right now i have the biggest urge to look behind me.

2. i think i suffer from hypochonria as well. ppl have told me, and i have taken a screening test and scored with it. i heard ppl with it often look up diseases and stuff on le internet in the fear that they have it, and they have the same symptoms therfore they must have it. i do that. right now ive diagnosed myself with so many. i know ocd ppl are afraid of getting illness. yes, that is me at times. but i know hypochondriacs are afraid that they HAVE something. THAT IS ME

and i forgot my other questions

you might...but on the other hand it might have just been something that happened in your past, that makes you nervous at certain times..because that happened to me after i was chased by a man in some apartments, now im always scared to walk alone, at night, with no one around....i don't think your sick or anything i think its just something like what happened to me, has anything happened to you??? well just in case you do have paranoia, good luck *** you can take that quiz i put on my sources:
