I'm sorry you're dealing with this. I understand why you think she might have canceled because she doesn't want to see you, but I doubt that's the reason. If it is, that seems very petty and also a bit dishonest of her. I would tell her what you're concerned about, both that you're concerned she canceled because you were too much to deal with and that you're wondering if you should quit because you feel you've ruined everything. I forget whether you can email her--if that's an option, you could tell her there, or else wait to talk about it next session. If you don't think you can say it out loud, you could write or type it and hand it to her.

You could come right out and ask if she wants to keep working with you. I know that's a scary thing to ask. And she might just turn it around, saying it's up to you, not her. But I asked my T this earlier this year when it just felt like he was sick of me (from some comments he'd made). His saying "I do want to keep working with you" and seeming genuine really helped me. (And he's not the sort who would lie.) And he said he thought there was still work that we could accomplish together.

So I'd consider coming right out and asking her. It seems like you're hitting on some important stuff in your work here. So it would be a bad time to leave, especially if you mistakenly think your T doesn't want to work with you anymore.

I hope you can talk to her about it and that she can reassure you that you haven't ruined things. And that she still wants to work with you.
