I've been a Pastor and faced great difficulties. Jesus is faithful. You will not be tried beyond what you are able to bear, though you don't know how deep that is till you get there. God will, with the testing, make ways of escape that you may be able to endure. You will come through stronger, with a more powerful testimony and ministry, if you allow God to work His perfect work in you.

There is gold that can only be gained in the fire. There is no other way. Praying for you brother, and your young family. God will provide. Look for unusual unexpected answers. You will get through.
