I suffer from chronic depression, probably for my entire life. I am now 69. I also have some problems with anxiety and obsessive-compulsive disorder. A year ago, I read an article on Asperger's syndrome (also called high level autism) and it seemed to fit me very well. At my age there is no benefit from a formal diagnosis which would cost Medicare and my co-insurance up to $10,000.
Over 10 years ago, when my cholesterol first went up, my doctor put me on Lipitor. I used this for about 5 years and didn't notice a difference until a new doctor took me off. I then realized that I had lost a noticeable amount of cognitive function and much of my ability to think creatively.
A few years ago, with my cholesterol still high, my doctor started me on Zetia. After about two years, I decided to see what would happen if I stopped taking it. While on Zetia, I had increased the amount of time I spent in thinking about killing myself. I also made several quite specific plans. Within a day or two of stopping Zetia, I was spending less time thinking about suicide and was no longer making detailed plans for it.
As a chronic depressive, I've thought about suicide as long as I can remember. I've saved some Zetia. If my physical health ever becomes bad enough that I might have to be locked up in a nursing home or other facility, I'll take the saved Zetia so as to achieve a more suicidal state of mind.
