I have been depressed for close to a month now. My creative juices have dried up(hence the sparse and unentertaining posting) and God seems miles away, even though I know that He is never more than an arms length away, and yet...
I remember my affliction and my wandering,
the bitterness and the gall.
I well remember them,
and my soul is downcast within me.
Lamentations 3:19-20
It goes on...
Yet this I call to mind
and therefore I have hope:
Because of the LORD's great love we are not consumed,
for his compassions never fail.
They are new every morning;
great is your faithfulness.
I say to myself, "The LORD is my portion;
therefore I will wait for him."
The LORD is good to those whose hope is in him,
to the one who seeks him;
it is good to wait quietly
for the salvation of the LORD.
Lamentations 3:21-26
I know that there is nothing of this world that will truly fill the void. Booze? Nope. Drugs? Nope. Sex? Nope. Buying myself stuff? For awhile, but then I get my credit card bill and I'm depressed again. No, my hope is in Him, so I choose to wait upon His salvation. I'm not very good at the quiet part: I beg God for His deliverance, I cry out for His hand of Mercy to heal me. I stomp and throw fits. I demand. But where else am I going to go but to the Lord? He has never failed to save me, so I will trust Him.

In these times it is never clearer that we war not against flesh and blood, but spirits and principalities. (Eph. 6:12). We may think we war against our own flesh and shortcomings, but it is a spiritual attack, and our enemy knows us well, and what buttons to push. But we know, too, that our own weapons are not carnal (2 Cr 10:4), but mighty through God to the pulling down of strongholds.
Meet the spiritual attack on the spiritual plane and pull down the stronghold by praising God, especially when it's the last thing in the world we feel like doing, and when the enemy is saying, in effect, "Curse God and die" (or beg, or demand). There is a time for reminding God of His word and His promises (reminding ourselves, mostly) but this is a time to "put on (choose) the garment of praise."
This can also remind you of your own "Ebenezer's" (see 1 Samuel 7:12), which means, "hitherto has the Lord always helped us." That builds your faith and your praise even more.
A small example.
Dave, the essays Ben referred to begin on page 48 and 51. I'd also highly recommend the prayers on pages 5-6. All these fit well with the link I left in my last comment.
If it will help, I'd be more than happy to treat you to a frothy pint somewhere.
