Need some general advice :/

I'm in a slump after what I thought would be an extremely progressive win streak. Have I peaked, or should I just take a break from chess?

Try learning more things, and take a break.

Thank you for the outlooks, strangers.

Your highest rating is 727, it is about +50 than your current. So you could do better. You were doing better.

I see you play 10 minute games. Maybe you should switch to 15 minutes. See if it makes any difference (try using all of your time, dont play a 15m in 5m)

A rating of 800 is a sign of frequent blunders.
Hang no pieces, hang no pawns and you are 1500 overnight.
Always check your intended move is no blunder before you play it.

Thank you, all. Very much appreciated. 

Play with more time control because it gives you more time to think about your moves. If you don't want your rating to drop, play with a friend. It'll help both of you.
