What's going on?

Hi everyone. Generally i am around 1400-1600 blitz with 1700 peak this year. i had some internet connection problems all summer and i started playing from my phone, witch i totally can't, but i'm a bit addicted and i really love blitz, so i dropped to 1400 blitz rating easily and i didn't care , then i started falling to 1300 and i said ''i  still don't care i play blitz for fun i'm on vacation keep going!'' Then my internet connection was fine and i started playing from my laptop again..well in 1 week im' close to fall from 1200 to 1100?? How crazy must i be? 1-2 months ago i was beating 1600's even a 2000+ in 3-0 blitz here and now i can't beat anyone, even with increment?? How can this be in the first place? I don't know how differently i play,  i just keep losing on time and getting mated from anyone, maybe i fear more and i don't get it? i even lost 10 in a row. I must play slow games and stop blitzing for a while maybe it's burning me. And watch Naka Vs MVL haha   Thx for any answers/advice.

It sounds like you're experiencing the common slump.  It comes just about as often as a cold and lasts just as long.  

Here's a useful post.
