Quick question-could be a trigger?

What happens when you tell your therapist that you've recently been self harming ? I had trouble with this a year or so ago which is what landed me in counseling in the first place. And I love it because I've gotten so much better but I haven't been able to speak to her since final exams so I've been dealing with shit on my own all summer and I recently relapsed..will she try to admit me if she knows I've recently self harmed?
