You sound just like me. Those were exactly my words 6 months ago. I'll tell you how that went. I texted her telling her canceling and then I emailed her telling her that I was quitting. She just say "good luck". I was hoping for her to be concerned and talk me into staying and so she didn't. I felt like abandoned me and that she didn't care. I said exactly what you said that its just a job to her. I left and I was miserable for
6 months. I missed her and my session and I had no one to speak to and no one to vent to. All of that time that I thought I wasted in my session talking I realized was really helpful. I was afraid of coming back and though I didn't get my "spot" back that I had for 4 years she did take me back. She told me that she was grateful that I came back. That made me think then that I was wrong. I wasn't just a paycheck to her. I actually was a person that somehow occupied some type of space in her world. What that space is I don't know and I don't want to ask.
I would touch base with her and communicate in some type of fashion and tell her exactly what you feel. You're obviously there for a reason and you feel the need to be there. So leaving might not be the best thing to do. Perhaps there's a miscommunication or misinterpretation. Give it a chance and find out. What do you have to lose? Tell her your fears.
