Therapist ghosted me?

I cancelled an appointment on short notice right before Memorial Day because I had an emergency at work and couldn't leave in time to make it to my appointment. When I texted her to let her know I couldn't make it she responded no problem. Then a bit later she texted that I would be charged a fee for not giving 24 hr notice. I didn't respond because I didn't think I needed to. The next week she emailed me and asked if I wanted to set up another appointment and that she was adding another day to her schedule. I didn't check my email for a few days and so I didn't see it right away. When I did I responded and asked her availability. She has yet to respond to that email. I don't know what to do now. One of the main things I go to therapy for is trust /abandonment issues from my childhood. I am too ashamed to email or text her again. I don't know what to do next. I had a really hard time getting therapy from her anyway because my previous therapist went to jail and left me feeling highly abandoned and unable to trust a new therapist. I don't even feel like I fully trust her yet anyway and now this. I'm in the midst of a large anxiety producing ongoing issue at work and I really need support, but what am I supposed to do? Sorry if I'm rambling.
