It's okay to feel anxious over something like this, but I think the best thing that you can do is let your therapist talk for herself. In situations like this, often our fears and worries come to the surface (and it's good to be able to work on them in the therapy), but what we think and feel belongs to us, not our therapists. We can’t read their mind or decide that we are taking advantage of them, only they know that.

Try to remember what your therapist has said about this herself. If she's offered, then I expect she's completely okay with it. The one thing that does actually annoy my own therapist a bit is if she makes a generous offer and I turn it down because I think I'm doing what's best for her. Sometimes I know it makes her feel like I completely reject her generosity when she's been willing to go out of her way for me.

I also started the year off with a $3000 dentist bill and lost a source of funding that contributed to therapy fees, so I've had to reduce my sessions, which has been really hard on me. I really hope you're able to enjoy and appreciate what your therapist is willing to do for you, even if you do have some concerns about it.
