Dors anyone know how YouTube works?

I looked up something on YouTube over a week ago. It turned out that it was very disturbing stuff. Maybe that was because I saw it right before I had a really bad prolonged 8 day panic attack that put me in the ER. I am certainly not saying that YouTube caused a panic attack. According to the psychiatrist I saw, the prolonged panic attack has a mostly physical cause and anything at all can trigger it. Also, I do have some serious stress right now from some things going on in my life. So YouTube isn't to blame.

However, I would like to NOT have anymore of what I accessed come up on my screen and every day more of it keeps appearing on my screen. It is stressful to see it.

Is there a way I can get YouTube not to show me certain subject matter? I know that if I ignore it, it will probably fade away eventually. But I would be much happier if I could avoid seeing it altogether. Can I get rid of it? Or do I need to just wait it out?

I am trying to remove at least some of the disturbing things in my life that cause unnecessary stress.
