Is it only a matter of time before expected feelings of "remorse or shame or guilt" surface during meditation?
I'd suggest that no-one can predict what comes next for someone in meditation. Perhaps there is 'stuff' that has yet to arise into consciousness, but if there is, there's no point trying to 'predict' what it is. That would just be unhelpful speculation.

I'd say, if you stick with sensing what is in your physical experience in a kindly way, if there's something there, it'll make itself known. In the meantime, just enjoy the practice :-)
