I know what you have gone through, trust me. I've passed enough pain in my life, twice with my stomach, and several other times for things like broken bones. One of those incidents with my stomach, lead to a surgeory as I had Appendix.
Trust me, I know how hard and scary these moments can be. I've ended up in hospital multiple times. Twice I thought I was going to die, prayed extremely hard, and was literally begging God to allow me to live.
Doctors told me after I recovered from the surgeory for my appendix, that if I had waited even 1 hour longer, I would've passed away, as my appendix would've ruptured.
I have also passed another surgeory before, on the back of my knee as I had a fluid there. I must say, I am very thankful to God, and the doctors themsleves for still allowing me to be here today.
