There are some meds that may cause delusions or thoughts of suicide. Among the possible side effects mentioned. Ever take any?

Yes.  I was diagnosed WRONG and given the worst things for my condition you can imagine.  This PSYCHIATRIST charged 90 bucks for 15 minutes.  Can you believe that? 

She asked me what my symptoms were ( I was going through menopause) and asked me what I thought I needed.  SHE ASKED ME.

I told her I felt like I was so nervous I could not think straight and I could not sleep right (I was missing progesterone) and she gave me medication after medication.  They all worked for a week or so and then made things worse.  Finally she gave me Lithium.  YOU DON'T GIVE THAT TO ANYONE.  Unless they are hopeless.  I got some and it sent me into such a fit of depression that even though I stopped taking it after a week or so, I suffered from this for at least 6 months.  Or longer.

I wanted to kill myself, but I was so depressed, I believed I would go to HELL and be depressed for good.  It was a nightmare.  And, I finally made it to another Old Fashioned Doctor of Medicine who gave me Progesterone and I took it and was fine that day and the rest of my life.  I don't need progesterone now, of course, but I took it to balance my hormones out for about a year.
