Hi Brother,
You have been missed.
There are certainly some very good answers posted already but I thought I would add my perspective as I recently had a wilderness experience myself where I did not feel numb exactly but more like a paralyzed confusion. My mind wandering, thoughts difficult to articulate and unable to concentrate on a matter sufficiently. I also had thoughts that seemed to rise out of the pits of darkness that I had hoped were behind me, this came right on the heels of some great discovery and fellowship which made it all the more frustrating.
As I prayed about it I was led to James Chapter 1, a few verses really spoke to me (the whole chapter is relevant though);
Jam 1:2 My brethren, count it all joy when ye fall into divers temptations; (Much easier said than done)
Jam 1:3 Knowing this, that the trying of your faith worketh patience. (This gave a glimmer of hope, the proverbial "light" at the end of the tunnel))
Jam 1:8 A double minded man is unstable in all his ways. (This one smacked me right between the eyes)
In meditating on this it came to me that this quest for knowledge and all the other gifts of the Spirit I had neglected a very primary directive, obedience. The commands of our Lord to selflessness, to help others, to be a small light in a dark world.
I got caught up in my own wants and worries forgetting the precious gift we have been given. We have a better perspective on Who our God really is than the great majority of the world does, He has given this knowledge to us freely, we did not earn it nor do we deserve it. With that knowledge comes responsibilty to others, we have an example of the most selfless Man who ever walked the earth and if we faithfully follow these commands He will take care of us in the here and now.
Mat 11:28 Come unto me, all ye that labor and are heavy laden, and I will give you rest.
Mat 11:29 Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.
Mat 11:30 For my yoke is easy, and my burden is light.
I also find Matthew Chapter 6 to be very helpful in times of distress, disenchantment or lethargy;
Mat 6:25 Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?
Mat 6:26 Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?
Mat 6:27 Which of you by taking thought (worrying, concern) can add one cubit unto his stature?
Mat 6:28 And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin:
Mat 6:29 And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these.
Mat:630 Wherefore, if God so clothe the grass of the field, which to day is, and to morrow is cast into the oven, shall he not much more clothe you, O ye of little faith?
Mat 6:31 Therefore take no thought, saying, What shall we eat? or, What shall we drink? or, Wherewithal shall we be clothed?
Mat 6:32 (For after all these things do the Gentiles seek:) for your heavenly Father knoweth that ye have need of all these things.
Mat 6:33 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.
Mat 6:34 Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil (trouble) thereof.
Do you know anyone who is lonely and could use a visit, even a phone call? How about an elderly or sick person that could use a hand with a chore or two? Is there a local volunteer group you could give a little time to? Things like this please the Lord exceedingly, we are sharing His yoke when we do selfless things and sharing His Light through our actions (not necessarily words).
I will close with the last verse in James Chapter 1;
Jam 1:27 Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.
His Peace and Wisdom to you, (you and yours are in my prayers)
Joe
