Hi 
I often say that grandparents should live forever. They give us a special kind of love, especially when, as in your case, they become responsible for raising us. It's wonderful that you've decided to dedicate your life to helping others with their mental health. The psychology profession needs people with that vocation, like you. Since you already have a good mentor to help you get started here, I'll just leave you with a little information and recommend these communities for you to explore: Hive Book Club and Hive Pets.
Tips and information as a Hive newbie here: newbie guide.
Communities you might like that are part of the OCD Communities Incubation Program. Important: read their rules and post in the one that fits your content.
Have a good day!
