"Knowledge is a process of piling up facts, wisdom lies in their simplification."
In time it will get easier. The ignorance has been washed away and you're going through a time where you don't know what to do with the knowledge. Accept it as it is and don't fret about it. These things didn't just appear when you learned about them, they were there all along, you were just blind to them before. Nothing has changed. The only thing changing is your own perception. Ignorance is not bliss. What we don't know can and will hurt us. You are better for your knowledge. Now you need to work on the wisdom of it all.
Knowledge is also hard to handle when we don't know exactly what to do with it. I suggest that you read into philosophy and gain a deeper understanding on life and people. I didn't look into philosophy until I was 18 (when I entered college) and I wish I had done it sooner. It changed my whole perspective. Aristotle, Socrates, and Plato just to name a few. Magick is centered around philosophy. Philosophy is woven into the fabric of the secret/sacred sciences. Without understanding, knowledge is pointless.
