Oh that's fine.. to call them challenges... some ppl call them "opportunities for growth"... they are struggles to me... but I don't see them as being barely hanging on issues... not the issues but sometimes me! hehehe
I'm sure having a brain freeze at this point in your healing could be "shocking" or "upsetting" even... but of course you know that it is another level of discovery. It can be scarey also, as this may open up a whole new area of memories and challenges that you had no idea were there. I hope not, but it could be... and you can work through those too, if they are there!
Sometimes a slow thaw is faster than a "microwave."
