I have to say that I really relate to this. I have been treated badly and abandoned by therapists in the past. I am struggling in my current therapy immensely to trust.

But I think that there are two things that are important to realize. First abandonment or feelings that the other person is not there can be created by things that have occurred in the past. When we enter vulnerable spaces like therapy these kinds of issues can come up big time. Have you been abandoned in the past either emotionally or physically, if so you maybe reliving some of those feelings now, and you need to tell your T. Second, therapy is like any other relationship, if something is bothering you in the relationship, you need to find away to bring it up. And while it is true that actions do speak louder than words you need to create a venue for those actions to happen by bringing up the topic. If you don't do that then your T has no way to act. I suggest as others have said that showing her this post might be a good way to accomplish that. If she doesn't respond with concern or in some other way that reflects the importance of the issue that you raise, then it might be a good idea to go else where, but I really think that you need to give her a chance first.
