(((hugs))) It's okay with God is you are angry with Him. It won't do you any good though. God says to "bring it on" and He will show you what you want to know.
I believe God created all things, and He said all things were good.
It wasn't He who caused things to go downhill, though He did provide
the Solution.
The body is a finely tuned machine, and when any one thing goes
wanky with it (professional term

) then it has a domino effect.
Allow God to use your weakness to rely upon Him.
God doesn't find pleasure in the suffering of those who are seeking Him.
