It IS super expensive. When finances become tight, or the bill becomes stressful, I would encourage you to talk with your T about maybe how to manage? That you do find value in going, but at the same time, this can be a major stressor!
Allow yourself to really examine if you're getting the 'bang for your buck'. If your sessions feel helpful, focused, goal orientated, etc and symptoms are resolving or atleast going down that path - how do you price tag that?
Still - expenses like therapy, can be a huge source of stress.
