Inner Guidance

So I've been doing readings for this one person for a while, who asked me to help her. In the beginning, I enjoyed getting the chance to practice my abilities. However, I noticed that after a while of responding back and forth, I started getting really angry about the whole thing. She wanted me to look at her pictures, and when I did, I felt like someone punched me in the stomach. I intuitively get the sense that she has been draining me, perhaps unconsciously (energy vamping?), but it was there. I decided to do another reading on her, and then I ended early today and told her I need some space and time to myself, and that she can do it on her own. I felt like she was beginning to latch onto me in a dependent fashion, and I just had to get some space. The feeling is beginning to subside now; I'm learning that taking care of yourself is CRUCIAL. It's interesting because I've been through similar experiences before in the past. I wonder if it's like a mini-test from the universe to see how I would handle it.

Has this experience (or one similar) happened to any of you?
