Very interesting. Thanks for posting.
One of the greatest difficulties with medications for mental health is that people take their meds, feel good, so they stop taking their meds. This is especially true with bipolar and schizophrenia patients.
Thus, you must be open minded in that the meds may not be the cause. The cause is stopping the meds.
If there is underlying anger, meds will NEVER take away the anger. They can only temporarily block it. The same is true with the feeling of grief from loss or depression.
Be careful as correlation does not mean causation.
Crazy people take meds. Crazy people do crazy things. The meds may not be causing crazy people to do crazy things.
