Does anyone feel the same way: I grew up in a day home and feel emotionally unattached to my parents.?

I was placed in a day home from about 6 months old until I was about 7 years in order for my mother to go back working two jobs, and my father to his full-time job. The family that helped diaper change me, potty train me and begin to teach me life skills was excellent. Although it got to the point where I was there from 8am to 6pm or later every day, which caused me to become confused and even call my day home caregiver "Mom." Even though my parents are very loving and caring, I still struggle with being isolated most of the time. Now I'm 19 years old and still feel emotionally unattached to my parents and feel I have subsequent behaviors that have left me with a life-long suffering of Depression and emotional insecurities. I can't express these feelings with my parents because it only makes them feel guilty or will cause them to reject my depression. Is it normal to blame my behaviors on my upbringing and my lack of physical and emotional attachments?
