Life after loss

Hi everyone. In need of some support and advice. My wife and I started ttc for our second in December, life has been great, we have a home, healthy marriage and a 16m old. After our loss in January things have changed drastically, we are both struggling with our mental health and I’ve gotten to the point where I don’t want another baby and even more I want out of the marriage. I feel aside of myself. A different person that I don’t recognize. I’ve struggled with depression my whole life and never knew true stability, so any kind words or advice would be truly appreciated.
