Keeping Support or Change Role?

Hi guys! i Just have some thoughts in mind and (usually) sharing them here gives a useful feedback To me...so here we go!

Lately i find playing support really really stressfull. (Soraka, Nami and Karma My best picks) I really fill The more i climb, The more i hard for me To have any impact in a game...no matter how i play, mid top and my adc plays have such a weight that i cant change the game flow At some point.

So...I cant prevent a Snowball from feeding lanes and so on. But in lane im still very confident on what and im doing!

Many Players i face tell me To change role. I did a lot of experiment in every other lane. But i lack The confidence, i'm not always sure of my plays and i tend To play very defensive, Even if i dont feed. (one of the things i can do better, playing safe all game).

I'm really confused guys, what should i do? I keep being confident in what i do, even if It drives me crazy sometimes, due To The lack of impact? Or should i shift role, while not being 100% sure of what im doing and playing very (too much?) safe?

I mean, There are pro support mains...but its so hard To solo carry this days :/

i would really appreciate some advice. Counting on You guys!!!

i struggle To climb or have impact as a main enchanter support. Should i change role and Take The risk of not knowing what im doing?!
