Can I place my child in temporary foster care?

I am trying to handle post partum depression, but with a baby, I don't think it will ever resolve without some time alone away from the baby. I just wish I was never pregnant. I wasn't ready for my life to change like this, but I don't want my child to be adopted. I believe I can handle being a parent, I just need the help getting there, and that includes having the alone time as a person to help me overcome this. I feel so guilty for asking but has anyone ever placed their child in temporary foster care? Can I do this for depression?
