A few thoughts.
- I suggest scheduling some "review" weeks, where you don't go over new material, but recap key points and allow for group discussion. This gives you several breathers in the middle of a series, which will help you stay fresh as you're preparing material. You certainly should schedule some kind of break between series, too.
- I assume from your note that you're writing the curriculum for the 22 classes, which are led by others. If that's correct, then I would recruit some of your teachers/leaders to help you shape up the curriculum. Let them help you, for example, think up key questions which will guide participants to your key points and applications.
- In general, teach less material per session, and teach it well. Leave your class hungry for a little more! This actually improves learning and retention, but also means you're not so overwhelmed as you develop lessons. Focus on the key take-home messages.
- Do you have some good seminary class notes or do you have a sermon series you've heard on Luke or Isaiah? You could leverage those to help you build out a lesson series. It's all about tailoring material to meet the needs of your class at this particular time.
- Here's a fun "change of pace" to try one week: Have the class read the passage, then work together to produce a short devotional that would be appropriate for some people they know. You'll be surprised at how much they can learn as they study in order to teach!
- Plan for a mini-sabbatical break from preparing lesson series. Don't let yourself get burned out and frustrated with it.
- Assemble a prayer partner team to pray for you. You need this.
