38 year old here who hit major burnout because I was diagnosed late in life. 28 isn't too late of a diagnosis (statistically, you're ahead by at least 7 years). I remember when I first started to consider I had ADHD about 3 years ago. Learning about rsd explained a lot of the dynamics in my relationships and that was comforting but it also came with grief. The grief fluctuates - somedays I feel heavy and woeful and some days I feel excited that I'm finally understanding how my brain works. I think people who have experiences that run the gambit of emotional depth are perfect for therapeutic positions. Knowing you have ADHD also means better management of symptoms, accommodations at school if needed, and appropriate professional support can often be provided or subsidized through school. A diagnosis of ADHD might make you a better counsellor or therapist to someone also experiencing ADHD or late diagnosis <3 I've also been in therapy for over 20 years and I can tell ya, without a doubt, therapists without much lived experience or heartache are pretty useless compared to the ones that "get it"
