I hope you do not judge me for this . . . I have extreme depression, thoughts of suicide, but I hide it quite well. Tomorrow morning, I have a 7 a.m. appt. Just now at 12:02 a.m. midnight, I decided to look up the drugs they want me take for my deep cleaning of my 2 quadrants. It is Halcion. I did not tell my doctor or my dentist I have extreme depression and suicidal thoughts. Now I am scared to take this medicine or go in without taking Anything. I am terrified of needles and having 4 needles in my mouth makes me want to back out of this appt. On line it says this medicine makes you get more depressed. Laughing gas made me so depressed I started crying on the last dentist chair. He had to give me something else to knock me out. I do NOT know what to do. Take only half, or do a no show of the appt. What should I do?
