I'd definitely talk to your T about the money aspect. My T usually charges $150 a session, but her sliding scale is $100. While still expensive imo, it's $200 cheaper a month at least.

I get what others are saying about your mom not veing supportive of therapy or your feelings. But you can't change your mom. And if your parents are paying or helping pay for your therapy, then you're going to have to "play by their rules". So maybe try opening up to your mom about how therapy is helping you. And try to educate your mom about therapy. Maybe even bring your mom to a session!?!? My Pdoc never sees the patient’s family (unless they're the primary care giver). But she allowed my fiance to come in for a few minutes to educate him on psychiatry.
