Yes, I do think that they can do reading's over the phone. I don't have any personal experience but I have read that they do. I suppose the question is whether or not that particular psychic can do it. I would be cautious but if you have a recomentation that you trust, and you feel that it would help, then the only way to find out is to try it.
I, personally, don't feel that going to a psychic to 'see' the future is a good idea. I think that can leave you open to fraud at the very least. I do think that a good psychic might be able to help people sort some things out, but your future depends your chosen path's and journey's. While some of that may be somewhat predictable the future is too complictated, and too many variable's, to be predicted with any safety or accuracy. Just my oppinion. I do hope that you find what your looking for and if you call this psychic, I hope that he or she is able to help start you on a happier path. (((hugs)))
