Need advice from people on the internet

Hi internet, i'm sure this is the 10,000th thread like this but hey i'm desperate. So i'm currently bouncing between silver 5 and silver 4. Played about 200 games this season so far, and i'm suffering from the "idk what to play anymore" sickness. Most of games have been with either adc's or supports and recently i have been feeling like i should be playing another role. Can't quite make up my mind whether i just kinda suck at bot lane and should try something else. Or since i have Mastery 5 on 4 of the adcs i play just keep fine tuning the skills with them? I will admit occasionally i suffer from the "OMG that just went 21/0 and there was nothing i could do i need to play an assasin!"

But to bring it full circle i guess what i am getting at is....is it normal to kinda be undecided on wtf to do when you are just really starting out playing? For some background i've been around league for a while now but only really gotten into ranked the end of last season and playing this season.

Posted my op profile along with this so feel free to dissect and let me know what you think. Have thick skin so don't be shy.
