Spiraling crazily out of control!

On May 5th (after joining on April 30th) i reached a high of 1205 after winning one and losing one. Since then, i have lost all but two of my matches, both of which being through time outs, accumulating a win ratio of 2:14; and it is getting worse! Whereas, naturally, i want to be going the other way.

Has anyone got any tips or advise for me, it would be most welcome.
