Bankroll

[fbonacci]

back story- In august at one point I was up about 6k, for a 19year old who doesnt get to play live alot, this was a pretty solid amount. I was grinding out 1/2nl online, and decided to put my full bankroll inplay at a 5-10 game did well (2k in one night) and played those stakes for a week. I played a live 1/2 game in pittsburgh and cashed out over 1000. (This was all in a weekend), and then won 400 the next weekend at my regular 1/2nl in roanoke VA.
Anyways long story short I have now been on a streak where I cannot win a hand. I am down all of that profit, I have since stopped playing 5/10 and def. have been sticking w. 1/2 maybe 2/4. I just seem to suffer ridiculous beat after beat, I havent changed my style at all from the end of august when I could not loose a hand, I dono what to do. I feel like I constantly get my money in with the best of it but usually by the time its all said and done I come up short.Help please?
