Need a support coach

I'm a silver elo supp who is always looking for ways to improve my skills on league. However, I feel like I've seen every video and I have been playing for long enough that at this point, what would help my gameplay more than anything is someone in a higher elo to coach me on supporting. I play everyone but main thresh, leona, and blitz. If anyone would like to help me, just message me ig. ign Sloppy Joe
