Is it worth making a new account?

Everyone starts off terrible at this game, and this is the account that I did that on. This brought my overall winrate down by a ton and it's been pretty exhausting trying to get it back to where it is now, even though it still isn't even that high (45%, but from 36% to 45% in just a month or two isn't that bad of an increase).

I have been stuck in between Bronze 5 and Bronze 4 ever since I started playing ranked, even though I consider myself a semi-decent player for my elo and think I should be able to easily get to at least B3, but I haven't been able to do much even with a couple hundred games played (yes I know this isn't many games compared to some but still, I think you get my point).

I also have invested quite a bit of money (for me) in this game and I really like all the stuff I got from it and whatnot so that's another aspect stopping me from making a new account.

Anyway, is it worth making a new account even after all the time I put into this one? I just kind of want a fresh start but I also think I can make this account work if I just keep playing. Like if there was a way to reset everything but keep the skins and shit I would do that but I don't think that's an option.

Let me know what you think, and my op.gg is below if you wanna see my stats and shit for some reason. http://na.op.gg/summoner/userName=itsMojoYT
