Thanks for your answers, guys.

I'm basically depressed over philosophical skepticism. The idea of Solipsism in particular. I know that philosophical skepticism it's not just that one idea, but I'm not really informed over the other ones.

I think my main problem is that I've started reading that stuff believing it was the truth or something, and I kind of get stucked over it. I also think that, as you said, is all related to OCD.

Thanks for your help.
