It's just my opinion, but if you can afford it and daughter wants to stay in therapy, why not let her? If money is an issue, perhaps she can contribute in some way. It really does take a village to raise a child.

There may be issues your daughter needs to discuss that have nothing to do with your parenting skills or with you. It's my opinion but, whatever it takes to have a healthy child, mentally and physically, we should do that as a parent.

I know it is hard not knowing sometimes and it's hard feeling like we are losing, either control or knowledge of our children as they grow, but it will be worth it to give that up for the wellbeing of the child. My son has been in therapy since he was 8 (he's 19 now). It's worth it. It doesn't mean you are a bad mom. Sending your daughter to therapy in the first place shows how much you love her and want her to succeed. Allowing her to continue will show that as well.

Feel free to PM me any time. Best of luck for both of you.
