start. Consider that your present hopelessness is sin. Either you have put your trust in something other than Christ, which is sin, or, like the Israelites in the desert, you have essentially said that what God says is not true, which is the sin of unbelief. God not only forgives these sins against him, he empowers you to put your hope in him. In your despair, can you ask God to give you grace to resist sin and trust him through suffering?
