Hey there Mandy!
I noticed you mentioned your bouts of depression seem to come in 'cycles'.....
My daughter actually is the one who brought to my attention that she noticed my pain flares and depressed state of mind seemed to come in regular cycles....so I started keeping a 'mini-journal' of my moods and meds and what type of activities I've done, etc and sure enuf, there was a connection.

Part of it, (I'm sure you've been told this) is hormonal......yes?

I've also seen/heard from others that the weather has a part in it.
Example: when we have several days in a row of overcast sky, depression seems to flare. Lack of vitamin D from the sun i guesss.

.......Sooooo ? What's YOUR 'theory' ..... the chicken or.....the egg ?
