One thing you should praise God for is His pardon! Through the death of Jesus on the cross God has forgiven all your sins! And by His wounds on the cross and because of His resurrection you have been healed!
Even though you deserved judgment because of your sins. And part of that judgment is sickness and death.
But instead, God in His great love and mercy, sent Jesus to absorb the penalty for your sin. And the judgment for those sins was laid upon Him!
That is worthy of praise!
