Dear Kerry,
I am a caregiver too and know exactly what you are going through. Caring for my sick husband was the hardest thing I ever experienced in my life. I got to the point where I could do nothing but cry (not in front of him, although sometimes he knew I did)and take care of him. After 2 months of this I went to the doctors and he prescribed Lexapro for me and told me I should have been to see him long before I did. It was a great help! Please take care of yourself and get some help to get you through this. Things will get better. Leon is 2 months post treatment and I am starting to see a major difference in our life. I agree with Marcia, your husband needs you more than your kids right now. Accept as much help as you can from your parents for caring for the children right now. It's not forever, it just seems that way right now. Take care!
