You were made on purpose for a purpose.

“And the LORD said unto him, Who hath made man's mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD?” Exodus 4:11

You were made on purpose for a purpose. God has a plan for everyone. Even those that human society says they have no value. Who are we to say who has value or don’t. God is the one who assigns value. And God says I made them on purpose.
They’re not a mistake
They’re not a happenstance
They’re not an oh I should’ve had
They were made on purpose they were in your family or are in your family on purpose
