I was going through some used towels in my garage today, they have been in there for a couple days.

One of the towels had some what looked to be blood on it. I cut my hand earlier today also.

I should also mention that I have OCD. I'm just wondering if it is possible to get it that way.

All the towels were bunched together in a bag and its pretty damp out there. does this make a difference??

Please forgive my ignorance.

I've just recently gotten this obsession in the last year.
So I'm trying to learn about it to combat my fears...

TIA
