Do you guys have a constant winning/loosing streak?

I'm really new to this, and whenever I play, I realize that I always have a streak of games in which I'm either really good or really bad. It's like I'm playing really well and making the best moves, and then when I lose a game, I want to keep on winning. So out of frusturation, I play more and more games and that just results in more losses and it's like a vicious cycle. Do you people have this experience as well? 

Whats a winning streak?

I often go on long winning and losing streaks. Right now, I haven't lost an online game in 5 days:

And it's not like I've been playing perfectly either... I've made at least 1 serious mistake/blunder in every one of these games.
