Hey dude, I used to be like this too, long ago back when I was trying to level up to 30 as speedily as possible. I played a few norms back in the day and I got verbally harassed quite a bit and also didn't like the fact that I would go against the same champions all the time. So I decided to play bots, and ever since level 15, all the way up until level 30, I played bots ALWAYS. Then, when I decided to muster up the confidence to try playing normals again, I was AWFUL! It took me about 3 months to actually get relatively good at the game and get acclimated to normals, which involves quick reactions and decent strategizing. If I have any words of encouragement for you, DONT PLAY BOTS. EVER. They are so easy that when you do decide to play normals you end up performing terribly because you're so used to the idea of horrible opponents. I'm sure you'll get better if you keep practicing IN NORMALS. After a while you should eventually be great, honestly.
