It's heartbreaking to here, and to think of, including imaginging the child. FWIW, from some random person on the Internet with no expertise, and without knowing you at all ... one of the best things I've learned is to start with the relationship with yourself. Have compassion for and love yourself (in a healthy, not a narcisisstic way). That's a relationship you always will have, no matter what happens outside, and as it grows you can extend that love to others. Maybe that's helpful (and maybe you've already heard that!).
