ENDGAME analysis..

This is a recent game of mine,,I wonder if I could have won after making a blunder ,please help if you even think that I had chances of a draw..

I believe that if instead 27. Ng3 the position would be equal and you might of even had the slight advantage with less pawn islands. 

In your analysis you said you didn't know what 2.f4 is called in response to the sicilian opening line (1. e4, c5).    It is called the Grand Prix Attack.  It was made popular by British Chess players in the 1980's, however, since then black has come up with strong defense for this opening.

I would say that rather than to move the knight in that situation you should've moved ahead another piece. In this situation you had a slight chances of it being a draw but the chances were slim considering the fact that he was up in pawns and in pieces. Losing that knight is what killed you in the game
