No. You are are gold player. Accept that. The best way to get advice is with VOD reviews, but I have some general advice here: Bronze - Sliver - Gold ranking guide
For me particularly, I got from gold to plat by switching to LFG so I can better use my “life experience” and “leadership skills” to push the kids with better mechanics than me to shoot the right targets. I’m also a dad gamer. I don’t know how transferable this advice is, as it depends on your exact situation and abilities.
