Heh, no problem. The funny fact is, I always face a writer's block whenever I'm unsure of how to proceed. However, when I'm done planning the next story bit, and when I have a better grasp of the whole story arc, I never experience what we call a "writer's block". It's just a matter of writing things out after the initial planning((with loads of editing, of course -you can't do away with that stuff XD).
One more bit of advice: don't plan things out fully. One thing that you could do, is figuring out the main plot points that your story HAS TO go through in order to reach the final destination. After that, you just need to know what the next chapter is all about... and then you can draw it. Or write it. However you want to proceed. I find that once I'm writing the next chapter, I start forming a better idea of what comes after... and the momentum just picks up automatically. When in a slump, however, I recommend stopping for a while and checking where the mine cart goes off-the-rails. Then you fix the issue.
But I think this is enough patronizing from me. I wish your writing/drawing attempts all the best!
