Welcome to the forum and good luck.
As others have hinted, with a bankroll of $50 you really ought to play tables with a $5 buyin at the maximum. I understand its replaceable and not a significant amount of money for a full time working professional, however its best to start good bankroll habits early and stick to it.
Best things to do early to improve your game:
1) Get poker tracker, log 10k hands and post your stats on the forums, any obvious leaks will no doubt be pointed out
2) Don't bluff at the micro limits
3) Post any hands you are unsure about in the appropriate forum
4) Don't bluff at the micro limits
5) Read everything here:
6) Did I mention never bluffing at the micro limits?
