Should I give up?

After not doing so well on ranked, I thought to just try out champions I havent tried before....and I came to the conclusion that there is not a SINGLE champion that Im decent at. I get stomped with every single one. 117, I have tried 117 champions in total over the span of 6-7 years. I know there are more but those just don't appeal to me in their visual department.

Should I just give up at this point? If Im doing badly, I just get yelled at all game, people tend to report me cause they think Im trolling....even though Im not.
