Typical Swings at 50NL?

[O.T.G.]

The past 2 days (about 6K hands) I've been raised almost every time I c-bet with nothing and force folds when I c-bet with a hand. It sucks to keep getting check raised and re-raised by players with like 0.5 aggression. It sucks when they are hitting 2/3 of their flops instead of 1/3 and are 2:1 to hit their set instead of 7.5:1, etc. etc. Sorry for the rant.

What is a typical downswing for 50NL on FTP and what is a typical number of hands to break even for?
