I sometimes have a weird obsession with sicknesses/ways to die. In january, I was scared of having Tetanus and now I'm scared of having a stroke and dying. Is there anything I can do to stop thinking about it? I check if I can smile every hour, sometimes only one or two times but there are times when I do it ~20 times in 30 minutes. I can't really sleep because of it.
(sorry if this sounded stupid but I'm having a really hard time with this)
