Is it normal to feel nothing?

:/ I don't really feel any love. I don't feel that "can't immagine without them" and "head over heels". to be honest, I almost wish everyone except animals would shut up and stop yapping their annoying mouths. I hate what they have done to the planet. To animals. To everything. To be honest, I don't feel any emotion... regret? no. Guilt? no. Joy? no. I can say that's funny, and laugh like i mean it, or that's cute, and smile, but inside me i feel like i have no proof to back it up. I feel nothing emotional, only physical. Nothing spiritual either, if you were wondering. I was very sick as a baby. Had to go on different medicines. I was in the hospital once a month, every month, until I was two. I've had every childhood illness in the book- even osteomiolitis. Sometimes I wonder if that is what is blocking my emotions, and what might fuel my 'hate' ( as i can't really call it hate, seeing as i really don't feel it.. it's more of a 'you could all go away an i would have no problem with it' sort of thing. ) towards humans.
