Scared at mark on toenail (health anxiety suffer)

I'm very worried about what this is on my right big toenail. I have had for quite sometime about 4-5 weeks and I only really got worried about it the other day.

I cannot remember inuring myself of the top of my head but I'm quite clumsy so could have. I have taken to google and have found all sorts of scary things such as subungual melanomas etc.

It hasn't got any bigger or anything. Looks like blood and doesn't hurt.

I picked at I know I shouldn't have and felt like I scraped some of it off, but I don't know. I'm just panicking and can't relax. Male / 22
