My mother is crazy and so is my grandfather (mother's father). I feel nuts sometimes as well, but I've always attributed it to my imagination. Where as my mother and grandfather show everything from angry out-bursts, paranoia, deep depression to bathing with Tide (the clothing wash detergent).
I pretty much feel this is something that gets passed on - craziness. If the craziness is from a physical disease, then its understood. But, does anyone feel mental illness is something that is passed on to children?
I basically don't want to have any kids, knowing that they may be crazy. It would hurt me pretty badly knowing any children are given something that harms them, let alone my own flesh and blood.
