Do you have any specific questions about low-buy that you'd like to ask? I'm happy to discuss.
Also, I feel you on your body not behaving as you had expected. I've had an accident and a lot of surgeries/complications afterwards.
I literally went from super athletic and strong to feeble and frail. I cannot trust my body at all and there were days after the accident that I cried from frustration because my body couldn't function at even a basic level, so I was always on edge about the next time I may collapse or the next complication I would need surgery to correct. It's hard and frustrating.
I am working on regaining my strength and slowly learning to trust my body again. I think I'm learning, above all, that whilst the complications I suffered were rare and I hated my body for failing me, my body has actually proven really resilient. I am here, in spite of the complications, so perhaps my body hasn't failed me after all. Does that make sense?
I hope you have a safe delivery. And of course your baby will bring you boundless joy that will make it worthwhile. Just give yourself and your body some time after baby, allow yourself some grace, and trust that you will get to feel like yourself again in due course.
