You are enough. Your daughter has everything she needs in you. Fun fact, a child's attachment needs can very much be met with just a single parent!! You're doing everything you can and it's amazing. You are more than enough for her and doing what's best for you is also what's best for her. You've got this -- even in the moments where you feel like you don't got it, it's ok to say that to yourself, sit in it for a min, then you'll figure it out! You can do this. You are everything your child needs.
I am ALMOST at my last straw and I have all those questions too š I keep telling myself my baby is alive and well, I feed him, play with him, sing to him, and shower him with love. Im sure you do the same thing so of course we are good enough! My postpartum has been rough and started going to a small english church and it has giving me strength and so much peace. If you can ever make it to a service or even a youtube service I am sure it will feel like a warm hug, hopefully š¤
