dero, your downswing sounds similar to the one I had a while back (~32 BIs I think). Here's a graph to hopefully give you hope for an upswing:
From 100k to 135k, my bankroll took a huge dive. Since then, I feel like I've really improved my game and I think you can see the difference in variance (and win rate obv). FWIW, this graph represents about 6 months of play.
