Never had an actual breakdown, but I've battled depression in the past and its completely joy depriving. I made it out of that time of my life, and I hope to never end up back there again. I completely isolated myself from everyone that loved me, it was the loneliest time of my life and I did it to myself. Had I only seeked help I would have come out of it so much sooner, but I feel more capable of dealing with those types of feelings now that I have conquered it on my own.
