Cyn,
One day you will catch yourself laughing at something...and will wake up...meaning remember you hadn't laughed like that in so long. That was the way it was for me...finding the laughter again. Don't know how long it had dried up, but, once the rains began, spring came again.

For me the meds didn't 'fix' me, nor did they dull the pain.
What the meds Did Do was let me so more than one option. Instead of sleeping all day, I slept in, then got up...hour or so later. Instead of seeing too many choices in something...it helped me clear my head enough to be focused enough to pick something. *old story tell later.

Meds, brought me back to the edge, before I tipped over and into the abyss...allowed me to hold back from tipping long enough to think through the stuff that was happening...find solutions...acceptance....even find giving up...and being ok with whatever happened.
The meds do Allow me to bounce back faster when I do slip into the depression. I don't obsess over and over the same thing...helps to go through therapy...CBT...Eye motion...
If I find myself obsesssing over something...I find some way to distract myself...until I can get a handle on me, then the situaion.
Bottomline for me is; I can't do it all...There are some things I can't fix...there are some situations I just have to live with, accept and find a way to live with it, or accept and live without it.
