Claire,
This is a typical psychic scam I’ve seen for many years. I’ve met many people who have lost hundreds of thousands of dollars to these types of things.
First, don’t buy into “you have a dark cloud” sales tactics. This is where you get you. Everyone has issues and this person you are referring to has more than you – that’s my intuitive sense. They are simply trying to bait you into thinking you need them.
Most of these people don’t even have real training or experience. My hunch – this person falls into the same category. I would suggest getting away.
Don’t pay for any type of healing based service unless you know the person and there are many reasons to trust them. Even then, watch out. If the fees start rapidly increasing, run away as fast as you can.
As far as getting rid of negative energy, if you are really serious about it and do believe you need to do something about it (but not because someone else told you so), your best bet is to learn how to do this yourself. It’s not a huge impossible feat. There are training programs for this and sometimes you can find some decent books at the bookstore. Most people will benefit greatly from this.
