You're definitely not the worst player. You know that saying, "There's always someone better than you" or something like that? Well, there's also always someone worse than you.
One thing the Boards is not good about is giving advice. You see advice discussions very rarely, since most of the time the complaint discussions in Gameplay crowd them out.
Even though Youtube is a terrible place for having a discussion, it is a great place for guides. You can find some really high quality teaching content here, like SoloRenektonOnly and LastShadow9. Unfortunately, you need to be good about separating the wheat from the chaff here, because there's so much disgusting clickbait on Youtube made to generate ad money. If a title seems too over-the-top, don't click on it. A good example of a Youtuber not to watch is Brofesco.
r/SummonerSchool is another great place for learning. The LeagueOfLegends subreddit is just as bad as the Boards when it comes to circlejerk and complaints (except it focuses on complaints a little less and eSports a lot more) and you are not likely to find any good guides there, but SummonerSchool is a different story. It is a subreddit dedicated towards teaching players how to be better and most of the threads are going to be helpful to you.
Mobafire is sort of a meme because of its joke guides, but there are many legitimately good Champion guides on this site as well, and they're generally easy to spot. The best ones sometimes give lessons applicable to any League Champion like warding or playing the laning phase. The guide creators range from trolls to people who treat Mobafire guides like they are their life's work, and it's up to you to find the latter guides.
SoloMid is TeamSoloMid's site, and it has guides too. It doesn't have as many as Mobafire but they're more serious on average. However, the best guides on SoloMid don't come close to the best guides on Mobafire.
LoLClass is a great place for extremely informative videos from top-tier players. It's like Youtube but you don't have to weed out the clickbait videos.
Skill Capped also has very detailed video guides from top-tier players, organized for a strong learning experience.
ProGuides is a paid service but I hear it is extremely rewarding if you invest the time into studying.
Mobalytics is a personal improvement tool but it only works once you play some ranked games. It gives you personalized tips to improve based on the results from your past matches. Even though you can't use the tool yet, Mobalytics has published a lot of informative articles that could help you get better.
You can also try hiring a coach. Most coaches charge for their services and you will need to invest a time commitment, but you'll get unparalleled personal attention. Remember though, not all coaches are good and you want to make sure that your coach knows what he or she is talking about. Ask about the coach's track record if he or she does not provide you with that information initially.
You can use the Player Recruitment subboard to ask for a coach. Sometimes coaches post there and offer their services, so make sure to browse frequently. Sometimes they're working for free to get started and get a track record going, and you can potentially benefit from these coaches.
LoLTrainingHouse is a cool tool for finding coaches.
XsollaAcademy is another tool for finding coaches.
LoL Coaching is another cool tool for finding coaches.
Hope this helps!
they both are pretty easy to pick up and rewarding when mastered. If you can land his Q then 
are some of my fav champions. You can also try to jungle, 
as I'm reasonably certain most players enjoy hard cc. They will be harder to learn however, and jungleings a tough role to master.
