Something will happen. Accept it when it comes in. Even if your normal reaction to this stuff would be to push it out of sight at once. It may take many sessions over many months before you get good at it. Study the materials again now and then.
Solo processing takes patience.
The same actions again and again. If you get bored by that then really feel the boredom in its details until the boredom is erased enough for you to continue. If you focus on a pressure area and nothing happens, then just accept peacefully that nothing happens. Don't get irritated about it as then you surely won't get any erasure. Just confront the pressure area as long as it takes.
