Finding a new role

As the title says I'm thinking about finding a new role, but the problem is that I don't know what to try. I'm a Plat 4 (currently Kr Server) support main and I just keep getting this feeling that I'm not playing the right role, if that makes sense. Sure I got to Plat and its slightly above the "average player" but the feeling is killing me cause I'm very indecisive. Does anyone know of a test to take to figure out what role would be best based purely off of your personality? Because even though I've mained support for around 2 years now I still don't really know my "play style". I've looked for tests like this but they are all so straight forward, some of the questions are "lane or jungle" or "would you rather go against enemy champions or neutral monsters right off the bat". I don't know if a test like I'm thinking of currently is out there but has anyone heard of one or know of one? If not I'll take some feedback if there is any for you guys to give.

More info about me ~

• I've played thresh pretty much right when he came out and he is still my most played support
• Other supports I enjoy playing are Taric (the rework is the best), Braum, Alistar, Janna, Nami, Blitzcrank
• When I play with friends sometimes they make me jungle so I play Volibear, Amumu (that's pretty much it)
• I don't really rage straight out and flame people but I'm more of a passive aggressive guy, I guess
• I tend to beat myself up and tends to be over absolutely nothing (making bad plays and dying for it, overextending)

If any of you guys have any feedback at all I'll be more than happy to hear it. Thank you ^^
