Competitive sucks

I tried my best but I'm still stuck at this rank. It's not like I bottom-frag or I didn't help my team at all. Like how am I stuck on plat? I duo queue with my friend who is currently diamond 2 and even when I top frag against other diamonds and ascendants. I only gained like 16rr while my diamond friend got 18rr for being bot fragged. 2 years ago my rank was higher than what I'm currently at even before ascendant was a thing.
