I am a college student who no longer lives with my parents, but lives in the same town, going to college. I see my parents a lot and have a good relationship with them, and they help me pay my rent, although I pay for all other expenses myself.
Last semester, my mental health dropped significantly and I asked my mother if I could go into therapy. She seemed very supportive, and said she just wanted me to be happy. After several appointments, she asked if I would consider switching to a cognitive behavioral therapist, and we agreed that I would have a few more appointments with my current therapist (who I really like.) I didn't hear from her again, and as I had no interest in switching, I didn't look into it much.
There wasn't ever a discussion about specifics of payment. We overall agreed that she would pay for the first few months, and after that I would pick up the payments. I work a part-time job but definitely don't have a lot of money lying around. I didn't hear about this from her again, until a month ago. She got mad at me for not paying for my own therapy and said that she needed that money for marriage counseling, so I would have to pay for myself from now on. At this point, she also said that I shouldn't talk to my Dad about this because "he would say it is fine, but it's not fine."
From my view, the costs of my appointments per month isn't a lot of money (less than $100). This would be difficult but not impossible for me to afford, but my therapist tells me that my mother hasn't paid for any appointments so far. Today, I texted her and asked if she was planning on paying for any therapy. She said I had promised to pay and that it was "my luxury."
If I had known as I had gone that I would have to be paying, that would be different, as I would have put more hours into work and saved money. As it stands, I don't have any money, particularly because I was busy with school for the last part of the semester. I don't want to discuss the particulars of my mental health with her, as I have trouble expressing those emotions, but trust me when I say therapy is not a luxury, and I don't want to stop going.
How can I convince her to help me pay for the costs of the past few months?
edit: In the end, my dad came to me and told me he was the one to handle money. He told me he would pay for my past appointments if I pay for future ones, and said my mom felt disconnected from me and I should try and talk to her more about my troubles. Next time, I'll go to him, and ignore what my mom said - he doesn't get overemotional and doesn't usually get worked up over money. Thanks for the help, everyone!
