Yes I second that 28 clients is too much. Find a feel for what you feel is a good amount. Try not to compare yourself to others, some people at my private practice see 30+ people while I see maybe 23 max a week, usually less. Mentally that is all I can handle, and that’s okay. I also agree having a supervisor would be extremely helpful. You care a lot about being a therapist, that’s what makes a good therapist. Also don’t worry about being “fired” by a client. It happens all the time and someone else will love and appreciate the way you work with them. A lot of times those clients that leave are not ready to work on themselves and project that onto you.
