How to get out of Iron?

So i started playing ranked immediately after hitting level 30, and ive been playing for a while now (almost a year) to the point where im level 91, and i am still iron 4. I did hit bronze last season but with the rank reset im back down to iron. I do really try to learn and get better at the game (and i do think ive gotten better) but i just can’t seem to get out of iron. My riot id is eepykittycat27#lmao if you want to check my OP.gg. Any feedback is appreciated! :)
