i think you are asking a reasonable question - but i am not sure there is such a thing as "normal" when it comes to our reactions and ways of dealing with the aftermath of CSA. it seems to me that it is a case of "anything goes" - from what i have seen.
so - yeah - i guess having irregular or chaotic spurts of progress or moving ahead at uneven intervals in different areas is probly a pretty typical way to experience it.
it would be nice if it was more predictable or you could somehow plot it or plan it or something. but look - what happened to us was outside the rational and normal - so our reactions to it are going to be characterized in the same way - and the process of dealing with and repairing the damage is going to be the same way.
i have found that the best approach for me is to work on whatever seems to be exerting the most pressure at the moment - not try to organize it or control it. sort of go with the flow. my subconscious seems to know what i need to do next. that is very opposite to the way i have usually lived my life. i typically like to have lots more control - but it doesn't seem to work that way in this situation. i am learning to be OK with that.
try not to worry about it.
someone else may give you a totally different answer -
and they would be right, too.
we are all unique - that is the one thing we all have in common.
We are often troubled, but not crushed;
sometimes in doubt, but never in despair;
there are many enemies, but we are never without a friend;
and though badly hurt at times, we are not destroyed.
- Paul, II Cor 4:8-9
