Diagnosis help as a college female

Hello, I have struggled with ADHD all my life and finally was able to get tested today at my college’s health center, but as a college female it’s hard to get diagnosed with ADHD because “you have good grades.” I feel so utterly heartbroken and helpless right now and I can’t keep spending hundreds of dollars trying to get help when they just won’t listen to me. Have any of y’all been in the same boat. What should I do to get the help I need. I feel so invalidated and sad. I have an appointment with a Psychiatric Mental Health Nurse Practitioner on Monday, will this be helpful to me? I need medication I can’t keep living like this. Please help :(
