Hi there, I read your post to MaDonna regarding your cluster headaches... I know exactly where you are coming from as I suffer regularly from occipital migraines and many, many times, a migraine has sent me straight into a downward spiral into depression, it can be quite challenging at times.
Anyway, I just wanted to show you some support and say to you... hang in there as best you can. I wish you many blessings and most importantly, I wish you well and healthy :)
Namaste~
