Liam has it correct there, in my view. Just add more separate Focus Blocks to deal with those underlying beliefs and deal with them as well in parallel. No need to specifically stop one topic and start another.

In fact, you will find that those underlying beliefs you have identified are probably underlying beliefs for many other things that are bothering you too.

You can think of many of the things that are bothering you as being linked to each other a bit like a spider's web. Cutting the web in one place will start to weaken it everywhere.

Remember that there is nothing special about the Focus Block - there is no great mystical principle behind writing out statements in bunches of 12. Just stop them, or discard them, when you feel like it and start them when you feel like it...the only key is that playing with them should make you feel better.

I often have Focus Blocks that, when they get selected randomly for me, I realize that they are no longer relevant to me (for whatever reason) since the last time they came up. So I just archive them immediately and move on. If I ever need to go back to them, I can reactivate them into the system.

You don't get any extra credit from the Universe for completing them first :)

The reason why, in the Focus Blocks Method, that you re-evaluate a block every 12 statements by choosing the best-feeling statement is that it forces you to re-read what you have done so far (which can often help loosen up your belief even further).

And also, the best-feeling statement, as well as acting as the starting point for the next block, acts a valuable reference point to show you where that Focus Block can lift you up to, should your belief drop back in future to some previous level.
