I'm afraid I might have PTSD. I've been traumatized by some family crisises where my parents nearly died. I never thought it was a problem and it's been a few years as well. But a few nights ago, someone had a nosebleed and bled all over a sink. When I saw the blood, I freaked out. I closed up and didn't want to speak to anyone anymore. Our psychology teacher says I should see a professional but I want to work in a field where there's no way they will hire someone with a history of PTSD, so I don't want any official diagnosis. What should I do?
