Jenny McCarthy has revealed how she was pushed to her emotional limits by her son's illness, even wishing he would die.

The blonde actress hit "rock bottom" when seven-year-old Evan, who suffers from autism, was given medication which kept him awake for four days. He suffered hallucinations and would bang his head against a bed until he bled.

Jenny was so devastated by what was happening to her beloved boy, she thought it would be best if he died so he wouldn't be in anymore pain.

She told Cookie magazine: "I ran out of my house and into my driveway and screamed at the top of my lungs to God to just take him away, because I loved him so much and he was in so much pain."

However, Evan's condition dramatically improved after Jenny switched her son to a gluten-free, casein-free diet and he is happier than ever now.

She said: "I have him in every sport you can imagine for socialisation, but he is already one of the most social kids you will ever meet."
