ah...I read these post and relate to all of you. I have battled the depression demon my whole life, I'm 44. I've been on most of the AD's. Some better than others, combo's for awhile. I do well, then crash like most of you.
When the "low" comes, I try to stay busy, I walk extra ( although it is hard getting out of bed at times) I contact friends and let them know I'm low.
Writing helps and being grateful for what I have is best medicine.
