Jim, please listen carefully to David's words. There is no better way to say it - he speaks a deep truth here.
Satan will not give up your flesh without a serious fight - depression, anxiety, that sense of worthlessness - all tools of satan to destroy you while you separate from your sin and turn yourself over to God completely.
"Therefore you now have sorrow, but I will see you again and your heart will rejoice, and your joy no one will take from you." John 16:22
"These things I have spoken to you, that in Me you may have peace. In the world you will have tribulation; but be of good cheer, I have overcome the world." John 16.33
This last one is very important: "And not only that, but we also glory in tribulations, knowing that tribulation produces perseverance, and perseverance, character, and character, hope. And hope does not disappoint, because the love of God has been poured out within our hearts through the Holy Spirit who was given to us." Romans 5:3-5
The Message has an excellent paraphrase of the first part: "There's more to come: We continue to shout our praise even when we're hemmed in with troubles, because we know how troubles can develop passionate patience in us."
Passionate patience - the steadfast and enduring state of gritting your teeth and getting through the crap because you know God is walking with you, loving you all the way, as you come to fullness with Him.
Like David said... we're here for ya and praying for you.
