My sharp game.

I play blitz games and select sharp lines to retain more seconds in my clock. I play well I think but I blunder so many times that I have a pathetic ELO (~1200).

Give me some advices. 

First off, you're a risk-taker. That's not necessarily a bad thing; in fact, risk-takers create some of the most dramatic games that people tend to enjoy.  Perhaps you would appreciate the playing style of Mikhail Tal.  Try studying some of his games.

Second, play slower games, or play the games slower.  It seems to me that you have a great sense of what to do at various aspects of the game, but you tend to rush things without seeing the potential consequences of your actions.  For instance, 20. c4 seems to be a reactionary move, but better was 20. Qg3 threatening the d6 pawn and potentially forking the queen and rook on f8, as well as positioning your queen in front of black's king.  Now that you've played 20.c4, black can now control the a1-h8 diagonal, thereby freeing his slightly cramped position.

24. Rxd6, slightly better is 24.Qxf7+  I think that would give you a somewhat even game because you'll have more pawns.

You seem to play better than your rating.  You might be advised...don't make irrational moves to complicate a position when you are doing fine.  Simply make a move that improves your position.  You will do much better.  I liked your game.  You have a nice style, especially for your rating.  Don't venture moves like Bxd6 unless you are sure.  You can always consolidate your position, and then the plans are much easier to find.

You played a strong game. I agree you should take more time to think moves over.
The after 22. exchange was fully predictable. 

Though I understand your blunder problem all too well. playing less can make chess more interesting and worthwhile.
