Looking for someone who could help me get better

I'm lvl 30 but my skills say 14. I play with a group but all but one are much better then me and I feel like dead weight when playing with them. I'm looking for someone who is nice, doesn't have shit grammar, is patient with me when I get mad for not doing good, and is willing to play norms with me and not get mad if/when I feed. I "play" ADC but I'm not that good with it. I'm supposed to carry as the adc lol. I also play sup and mid. The champions I play are

1. Vayne
2. Ahri
3. Morg
4. AD Top/Mid/ADC lulu
5. Cait
6. Sivir
7. Ashe
8. MF
9. and experimenting with Yi (Mains order)

so if you have any experience with these champs id also love tips and tricks :)

we will talk on discord so if you don't have disc I'm sorry If anyone's interested and you're looking for more info or questions feel free to message me @Glowing Eyes#6087
