Why do i hate daylight?

It sounds like you have Eosophobia; the fear of daylight. I dont think many other people are like this, but the sun is very healthy for you! It lets your skin absorb nutrients and it gives you warmth, without it, there would be no plants, meaning no animals, or life, meaning no Earth. Be happy you have it, and try to get accustomed to it, you can walk outside in your backyard for mabye 10 minutes every day until you feel more comfortable to stay outside longer.
