Someone help me with this tilt

The tilt is too strong. i was almost gold and now i'm borderline S2 almost S3. Yea i main Wukong, i can also play Nautilus, but i haven't gotten comfortable with him jg or top and i dislike playing support. I need a bigger and better champion pool i know. Help me out.

I've been interested in trying out Renekton top and Olaf (top/jg), and like i said Nautilus top, i don't do so well with him jg even though he isn't that bad there. Also, i've played Voli jg which is strong, but i'm a scrub so i don't do as well as you would normally see a Voli do, but i do like him and the play style.

I only play top and jg and i think i'm only decent jg; i'm good, but not great at it. But i like it better then support. I used to play support a lot with Blitz and Nautilus but i started building up dislike for it and quit eventually after getting my adc fed many games and they just throw, which tilted me for a while and i just sucked at support after that. Early in my LoL career i played mid with syndra but was never any good. I've played Wukong mid before and done well but i don't do it because that's an APCs lane and if take AD there i fear my team would lack proper AP damage. I would try support and mid again though, i just need to have more options and different playstyles so when i meet buly Renekton, or op dunks Darius, or too much sustain Fiora, or any other champ that is a hard match up for me with Wukong i don't put myself in a disadvantage.

Thanks.
