Looking for chess "mentor"

Hey guys! I honestly hope this post isn't a rediculous thing to ask, and if it is, please let me know and I will promptly remove it. Anyways, I've been playing a lot of blitz recently, and I am just horrible at it (~900). I love studying openings though and chess in general, but I just don't seem to be improving. I'm sure one cause of this is that I'm never playing players better than me who don't let my blunders slide. My question is if there is any player higher rated than me in blitz who would be interested in just every now and again playing a couple games, and maybe just quickly telling me where I went wrong at the end. Also, because I play people at my rating, I never get to try out any openings I study because nobody else knows them (rightfully so, we have bigger fish to fry at our rating). So I think it'd be fun to play people who know openings as well. Again, I hope this isn't asking too much, but I would so greatly appreciate any people who would be interested in crushing a 900 rated blitz player a couple times a week haha. Thanks and have a great day!
