Hi, Sal.
My first training was as a counselor on a telephone crisis hotline. With callers who were in genuine crisis, we had a model to follow, and when the call was over, it was over. Then we had "VQ" ("validity questionable"), "B&L" ("bored and lonely"), and daily callers. They were harder to get off the phone, but we had a model for that, too. It was all in the training.
Later, I became a psychotherapist. Our "hour" was 50 minutes long, and there was a reason! It leaves you a bit of cushion for winding things up. If there seem to be issues left hanging, you're supposed to summarize them and bookmark them for the next session. If there is no next session, you give them to the client to take wherever he's going next. Anyway, that's all in the training, too.
I've read that the way to price psychic readings is to tell the client what you're going to do and how long it should take and for what price, and then you do that, and you charge that. If it takes longer to do what you said you'd do, then you take longer and charge the same. But what you don't do is try to cram 4 sessions worth into one session! No matter how tempting it is to try.

As in the other two situations I'm talking about, it's a matter of boundaries and realistic expectations, and it comes with the training.
Maybe you could get a book on crisis intervention counseling and work through that. Or take a course somewhere. It seems to me that the talking therapies are where professionals learn to set boundaries for their sessions, and that's what this is about. Also, with some guidance on dealing with persons in crisis, you won't feel as lost in dealing with such persons-- and they will definitely come to you! It is just a method, like anything else.
I don't charge money at this time, and I don't know if I ever will. But I would gladly pay for a professional's services if I wanted them. Devoting oneself full-time to any activity doesn't
guarantee competence, but it certainly puts one in a position to acquire skills that the layperson might not have. That is what I would pay for. I mean, there ain't no free lunch. If I want a dedicated psychic (or plumber or lawyer), then I have to pay, because psychics gotta eat!
BTW, I've read some of your messages, and I like the confidence that comes across in your readings. Sometimes we are too tentative. I feel that we should say, here's what the reading says-- this is it. And if we're wrong, we're wrong. We shouldn't be afraid to lay it on the line. You set a good example of that.
