Knowledge is actively harmful, but like a druggie you will still seek it out anyways. Your mother is right and clearly cares for her child. I once spoke to my normalfag brother about philosophy and he only replied "yea, but are any of these people happy at all?". He is of course correct, philosophy leads only to pain.
All conversation is manipulation, all motivations selfish, all interactions meaningless, free will doesn't exist, the mind exists only to torture itself, "hard work" is just genetics, being born with genetics is the same as being born with money, ultimately you know nothing and merely assume things are real or truthful. I could go on, but you can understand already I hope.
There are three kinds of people
1) Idiots too stupid to recognize anything
2) Delusional copers that create spectacular mental gymnastics in order to survive
3) Those who see reality for what it is, will experience suffering, pain, and possibly suicide eventually.
