Oh my goodness, this is monumental. I am so sorry. Do you feel comfortable saying anything more? Is there a reason you must end? Is this sudden -- did you know this was going to happen?

It's good that you've posted and asked for support during this very difficult transition. Obviously, a plan to continue with another therapist in the future seems very wise.

This will be a painful loss and you will grieve just as you would any loss of a significant relationship, and you'll have to allow yourself to do that. Are you talking to your therapist about this ending? Is she giving you suggestions, ways of coping, etc.?

Perhaps she could give you something of hers to take with you. You could ask her to write you a letter about significant moments in your therapy. Or, is there a small item in her office she might be willing to give you as a transition object? Sometimes these symbolic things can help ease the pain. Well, only a little of course. It's just one small suggestion. I don't mean to minimize all that you're going through.

I hope you keep writing and reaching out for support. I'm so, so sorry for the reason you had to enter therapy in the first place and for the loss of this special relationship.
