I promise you will get to bring his sibling home
I'm sorry you are here again and I know it hurts, I know the sadness you feel. Please don't feel like you've failed and please don't feel responsible.
Austin is protected from your pain and will help with your healing but it's ok to fall apart a little. Make sure you don't bottle it all up and cover up your pain. It's OK to cry. It's also OK to smile and laugh.
When the time is right to try again you will know and you shouldn't worry, Austin is ready too.
You should also remember the joy you have from your beautiful boy and try not to get distracted with the negative thoughts. It takes great bravery to start the journey again and trust me you are brave.
Remember the saying that got you through all the failed fertility treatments before; everything will be ok in the end. If it's not ok, it's not the end.
Trust the timing and trust your body, it gave you the greatest gift you have. I promise you will get to bring his sibling home.
Lots of Love
