Anxiety about paying for therapy

I’ve been in therapy for many many years since I was young because of my severe anxiety and panic disorder. I’ve had bad therapists in the past but the one I have now is great and I’ve had her for a couple of years. Her company used to charge me every visit and then they merged with a bigger company and it’s getting expensive. I live basically paycheck to paycheck, thankfully don’t have to pay rent yet because I live with my parents but I will be moving out with my bf soon so that and other bills will become an issue. I have a high outstanding balance with the therapy company and I have to call them today to figure out a plan so I can pay for sessions and not have them cut me off. I’m so anxious about money and not being able to have any money of my own in case I need something. Their payment plans are horrible and I don’t think they can agree on something that is reasonable a month for me to pay and plus I pay my student loans every month which does damage as well. I love my therapist and it would make me very anxious to lose her. I just don’t know what to do and I even have severe anxiety just calling the office to discuss this
