Post as much as you like and need; your posts and presence are always always welcome. No such thing as too much, really (unless you could post 1000000 times in a day, which isn't even realistically possible!) so no worries.

I am glad your counselor did take you on then, especially if she did already have a full case load. And for free of charge ..... that's great and probably relieves you of a burden. Maybe someday she will be able to have more time.
