Shadowknight911 has useful advice there. I would add on to that by saying:
1) Study tactics daily if possible.
2) No more blitz. Switch to slower games where you have time to think about the moves/threats etc. (Shadowknight's advice).
3) Try analyzing each game played (win/lose). You can post some on the analysis forums here.
Best of luck!
