repeat cesarean unsure

hi all, i just had notice that the American red cross -in my state-blood bank only has two days worth of bloody supply whatever that means. It’s honestly freaking me out. I’m 29 weeks pregnant due October and i’ve had a very physically trying second pregnancy. I’m worried about my health, tired all the time, i had long covid and mono and I was initially concerned about recovery - my firstborn was a 3 day labor with emergency c section.. i was in hospital for a week. I was much stronger then and it was before covid i was also younger not by much 35, i’m 39/40 now. I breastfed my daughter until she turned 3, not exclusively but kept it going because of the pandemic.. she had a lip and tongue tie at birth which was negligible I felt and i pushed through the pain to be able to breastfeed her. I don’t know that i have it in me this time.. i opted for a repeat c section in part because i don’t want to go through days in labor like before never getting beyond 3cm. it’s not helping that there’s low formula shortage, and now blood. I’m at a loss at what to do, and don’t even get me started on work. I have 10’weeks of unpaid maternity leave which i have to return, i’m not the breadwinner in my family my husband and I make about the same but i’m overwhelmed. i don’t know how us women do it, but i need some serious help destressing. To top it off my husband and i are in marriage therapy because he was unfaithful last year. So my faith is wavering in so many areas of my life. but I have a beautiful daughter and so is my baby boy on the way. i wish i had more faith in that things will be ok
