[LFM][NA][PC] Currently challenger 3 in doubles trying to hit rising star before season end

Been solo grinding doubles for a while, but having a hard time playing consistently enough to break out of my current rank. I'll do really well and rank up to Div 5, only for the next day to go on massive losing streak and go back to div 2. Hoping that someone can help me see things in my own play that I'm missing.

I'm usually available late late nights Eastern time and briefly during the late afternoon before I go to work. I can provide replays, queue casual, stream my gameplay, or whatever is preferred. Just really wanna get to rising star before season end. Any help that someone is able to offer would be greatly appreciated!
