The new you?!?

Hey... I consider myself a strong person. I quit both of my jobs to come back home and be with family. I am very hardworking but ever since I had my baby I just don't know how to get back to my old self! I had a ok pregnancy with the exception of her father being annoying. And no me and him are not together. I am home but I take care of her by myself & at this point I am so attached and don't think anyone's gonna take care other the way I am. I just feel really stuck.. Any advice!?!?
