I think I’m low intelligence?

I’m a CNA in the hospital, and I’ve made mistakes but I’ve learned from them. I work around sick people, I do blood sugars but I feel like the nurses put added work on me. I try to take my time. I try to be safe, although it hasn’t worked a few times.

I’m afraid I’m low intelligence cause I’m stupid and get corrected often, I feel like I’m slow and everyone thinks it. My therapist said I’d have to be average intelligence to be a CNA and to have passed the exam. I do have ADHD, and get distracted easily. I do have anxiety as well.

Is my therapist right?
