Recruiter sent my CV to my current employer

I received a linkedin message from a recruiter about a higher paying position in my field. I haven’t been loving work recently (lots of crying, anxiety about my work place, constant check ins with my manager) so after researching the recruiter and company, we had a call and I sent over my CV. A week later, I received a message from my manager asking if i was applying to other jobs and that she’d been sent my CV from this recruiter. The original company i applied for was not my current company (obviously lol) and now i’m so anxious about being fired. I’m already not doing great at work and being very micro managed (i had a bad period with my mental and physical health and it really did impact how i was treated at work) and now this has really added to the anxiety. Any advice?
