Hi Shamefaced...
I understand your feelings. One thing to remember is that we all go through "seasons." Sometimes, we may not feel a need or desire for God (at least, on the surface), but the need is still very real.
Sometimes, I don't feel like getting up and going to work.
Sometimes, I don't feel like doing my work well.
Sometimes, I don't feel like eating breakfast, lunch or dinner.
Sometimes, I don't feel like showering.
Sometimes, I don't feel like showing love to my wife. (yikes!)
But I do these things (and more) anyway...because it is a responsibility. It is important to stop viewing such things as restrictive obligations -- but wonderful opportunities. Could you imagine if you didn't have the opportunity to do such things?
I spoke with a brother in the Lord who was recently divorced. He had taken his wife for granted and "thought" that he didn't "love" her or "desire" her any longer. He said that he treated her like she was a "nuisance." She eventually became fed up with his lack of loving attention, so she left him. Now, this same man who didn't "feel" love for his wife is hurting because she is gone.
I suppose that many believers don't know how much of an opportunity they have to serve the Lord! We have freedom of worship, plenty of Bibles, churches, online sermons, Christian books, Christian CDs, homes, jobs, Christian families, and plenty of other "blessings" from God! Yet, I fear that we often take it all for granted as much as that one man did his wife.
Reading your Bible is not a "requirement" -- but a need and opportunity. You can easily turn away and place it on a shelf and ignore it. No obligation there! However, the need and opportunity have presented themselves to you -- that many people in history have never had.
Brother, during "dry seasons" like this, I would urge you to "keep on keeping on." The Word of God is our very subsistence for life! If you feel like you are "obligated," then read the Word like you would a book. After all, there is power in the words in the Word. It is like water to the soul! Remember that, through simple prayer, you have the opportunity to speak with the Creator of the whole universe! Nothing is off limits or off topic to speak with Him about! You can even talk to Him about the dryness that you are feeling! What an opportunity to pour out our souls like a drink offering via prayer and prayerful worship!
I will be praying for you, brother. However, I think that many of us have felt as you do. God will bring you through it! Be encouraged!
