The therapists I didn't stay with I gave 3 to 6 sessions before I moved on. That was enough time to decide yay or nay for me. I didn't have time or money to waste on a therapist that didn't work right for me.

The therapists I worked with long-term, I honestly knew from the very first session that they were going to work well for me.

Trust your gut. If it isn't feeling right still after 5 months, it may be time to look for a different therapist.
