Where can adults get tested for learning disabilities?
If you want to get accommodations for your apparent disability – start with your college disability services office. They will have people and clinics to recommend to you. If you want to pursue treatment for your apparent disability and you have health insurance – check with your insurer about coverage for testing. Given you are 19 don’t look for any major change to transform you. There are tricks to living with a learning disability, but my guess is that you have learned them on your own without any diagnosis.
