Lf plat Jungler Ranked 5s

Hey I am gold 1 but I am just stuck in the 5 final games to rank up to plat 5 I am a really decent player that plays jg mid and top. I stopped playing ranked cause I can't handle the solo play so annoying I get to frustrated because the level of play is not there. You can test me if you want.
