PTSD from birth of my daughter

Hello everyone! I just need to vent and blow off some steam and I know this is the best and most supportive place to post this. A year and a half ago I had my amazing daughter. The birth experience was traumatic to say the least. Long story short, after having an emergency c-section I automatically felt something was off. I was in unbearable pain and couldn’t even walk. I had to get a blood patch procedure due to leaking spinal fluid during the epidural.I was discharged from the hospital with a high blood pressure and a fever. A couple days later I returned to the ER with sepsis and an abdominal wall abscess. I had emergency surgery and was admitted for a couple days on Iv antibiotics and pain meds. I was finally able to return home and I still felt off. I had a wound vac on my c-section area and the home health nurse came to change the dressing. She took my blood pressure and I had such a high pressure she called 911 for fear I would stroke out. I was sent home with a still very high bp. I went to my Ob the next day and she admitted me to the hospital with postpartum preeclampsia and more infection in my wound. This time I was in the hospital for 3 weeks. My baby was not able to come see me much bc of rsv season and I was on a surgical floor. i developed horrible depression and anxiety. I still have dreams and horrible flashbacks. My husband wants another baby so badly, but there isn’t anything I want more than to have my tubes removed. My paranoia about becoming pregnant again has become honestly ridiculous. I feel so selfish and horrible. He is so against it. He threatened divorce. I just don’t know what to do.
