I honestly think it's time for me to take a little break, what do you think?

So about 2-3 weeks ago everything was looking up. I got in to Gold and kind stood around 20-40 LP in 5 for a day or two, then started to climb and eventually hit highest 4 around 63LP, then everything spiraled downhill. I was getting about 4 LP more per win than I was losing on a loss. Now it's completely opposite at about 16LP per win and -20 per loss. I'm honestly scared to play any more games at this point cause I fear of dropping back down to Silver, I can't even win on my mains for crying out loud. I play Irelia, I do good/decent and I still lose. I play Kassadin and do good/decent, lose. Play Rengar and do good and lose. I just can't find out what's wrong. This is genuinely the first time since I started playing League in 2012 that I'm asking myself what the hell I'm doing wrong or what is going on. I just can't figure it out for the life of me. Saddest part is when I end up feeding I win more games than when I do good....

Hell this is a true story. I was playing Irelia into Riven on Friday I believe, she had a Nautilus jungle and literally I saw Nautilus in the top tri bush and I got a little low and decided to go back, come back to lane farm for about 30 sec and then decide when Riven's CD's were down I would take advantage of that so I jump on her and literally 1 second after Nautilus comes out of the right top bush, and I was like wtf did he SERIOUSLY sit there for 4 minutes straight. No they didn't kill me but it's so tilting when your team can't win their lanes when the enemy has zero jungle presence in lanes other than top cause he's camping me and my jungle has been mostly ganking.

Anyways I've been playing other games this weekend trying to just relax and calm down a bit. Although I don't think D3 really screams relax, it's a lot less frustrating to play ATM.

TL;DR: Just a vent post, sorry if I wasted anyone's time.
