I marked a few in that list. (o) means occassionally.

I marked off:

Obsessions

Fear of violent or horrific images in ones mind.

Fear of being responsible for something terrible happening (such as I forgot to check something and then i think of the bad things that can happen because I forgot to do that one thing).

Fear of harming others because of not being careful enough (o)

Concern about evenness or exactness

Concern with a need to know or remember

Fear of losing or forgetting important information when throwing something out

Inability to decide whether to keep or to discard things (I really have to think about whether or not they are important or not).

Forbidden or perverse sexual thoughts or images (o)

Forbidden or perverse sexual impulses about others (o)

Obsessions about aggressive sexual behavior towards others (o)

Concern with getting a physical illness or disease (o)

Compulsions

Well, the constant cleaning of nails wasn't in there, so I don't know if that counts, but I'm always cleaning my nails to the point where of pulled the skin from under the nail off of the nail.

Checking that nothing terribled happened, or can happen

Checking that you did not make a mistake

Rereading or rewriting (to make sure I saw exactly what I saw, or wrote exactly what I meant to write)

Praying to prevent harm (o). Not the typical religious prayer, I don't do those, it's more like a mantra (if I used that right), nothing specific though.

"Cancelling" or "Undoing" (I won't say bye very often, it makes me feel like i'll never see them again, and if anything death or harm related is said, I have to think of good things to counteract the bad thought, but I usually don't allow the talking of death or harm to happen)

Putting things in order or arranging things until it "feels right" (everything has to be where it's meant to be, such as all the lotions and perfumes where they need to be, or my oils all in the same place facing the same way in an alternating order, but i'm not a neat freak).

Telling, asking, or confessing to get reassurance


Those were all the things that I could find I relate to, without overthinking it too much (I may have unintentionally over-exaggerated some of the things)

I don't know if they indicate something, or not. Just figured you'd like to know what I decided to mark off. . . .

If you'd like to know some of my minor "quirks" that I do, you can just pm me and I'll tell you.

Best to you, and thank you for the information.
