Before I was diagnosed with severe sleep apnea, (I was spending only 20 seconds a night in REM) I was so depressed I was almost non-functional. My GP started me on SSRIs. Theyre supposed to take days or weeks to work. But with each passing day it felt as if all the weight in the world was lifted from my shoulders. After a week I began to wonder exactly how much weight Id accumulated and when Id level out. But having been depressed and taken SSRIs heres may take on what happens to people who start killing. If youre not a killer to begin with they arent going to make you one. Depression takes you so low that perhaps people who react when theyre no longer depressed started with ideation; fantasizing about either killing others or killing themselves. But theyre too depressed to do anything. It was, for example, all I could do to go to work. Every day I had to concentrate so hard at work just to make the decisions, fill out the reports, sign the timecards, etc. that it doing so was all I could do. But once the SSRIs kicked in I was back to really interacting with people, proactively solving problems and looking days or weeks down the road again.
So, theyre depressed. Theyre fantasizing and suddenly they feel better. Thats when they have the energy to act on whatever is in their heads.
The drugs didnt put those ideas there. They just made the man feel good enough he could act on them I praise God for SSRIs. (And, later for a CPAP.)
Be careful there, from my experience, SSRIs are a form of dulling guilt. With SSRIs you can do anything and not have any guilt.
You said you had a general practitioner give you the SSRIs, that is a red flag.
When I called Kaiser and told them that my wife was not acting normal after 28 years together, they would not talk to me.
Look up Serotonin Syndrome. It's as bad as taking LSD if it occurs. What can trigger it? Something as simple as being on antidepressants and taking an OTC cough medication among other things or just an intolerance to the med itself. I've seen someone go through it. The person under the right conditions could have killed. Why? Because she was seeing the devil.
