It can take way too long to get a dx, and that will depress neone, but pain can also cause
depression....
and last as I already mentioned, the compression of the brain stem can cause
depression as well...not to mention that the cerebral tonsils also affect emotions,moods, etc....we can have ours go all over....it is a roller coaster ride like no other.....
I did not find a med or a therapy that worked, helped, whatever....surgery and releasing the pressure did ...JMHO of what worked for me.
