Please get help
If you feel like you hate your baby please talk to your family about your feelings and seek treatment from your doctor or hospital as soon as possible. It sounds like you have postpartum depression.
If you are having these feelings it is nothing to be ashamed about but you do need to seek treatment. Postpartum depression is treatable. Postpartum depression can escalate and become dangerous for both you and your baby if left untreated.
Please talk to someone as soon as possible.
