Are psychiatries alright? What should you expect when you get in? How are suicidal patients treated?
Prone to suicide you say? They look you up for your safety and you never see the light of sunshine again.
Just kidding.
How do expect them to be treated? He will talk with, see what's wrong, see if you should take some meds or not, talk about alternatives... I don't know your history, but perhaps the doc will decide that drugs are not the best solution for you, and that you could simply have a better hygiene of life.
You should not be afraid, they are here to help you.
