When I was a young teen a doctor referred me to a psychologist. My mother felt the same as your mother. Like you, I was excited to finally talk to someone. I knew there was something "wrong" with me. I didn't know "what" that was.

I couldn't or didn't get the help I needed until I graduated college. I wished I went earlier. Although to most people I am happy and successful, I can't help thinking my high school and college years were taken away from me with my depression and anxiety.

Trust yourself. Your mother is scared. That is her issue. Please listen to your doctor. Medication is great. Medication with talking therapy is ideal.
