I was having the same problem with .01/.02 NL. Ran into a downswing and kept getting slaughtered by either players like the one you're describing or by calling stations catching the goofiest T3 two pairs...
Playing tournaments is good advice. Rather than sitting with the $5 buy-in at .01/.02 NL 6max, I've been playing the $5 27-man sngs on stars. My record so far has been pretty damn good in those (two seconds, a third, and two fifths in the past three days...maybe $75 in money won in maybe 12 tournaments at the most). They're super soft and the goofy beats aren't nearly as likely to send you into dejection.
My
anyway.
