It's never too late... I was the same as you... My struggles started in about grade two.. I continued to scrape by and make it to complete my Grade 10, but feeling like I was just plain Stupid, Hating every year of School & With no hope of continuing my Education.... . I even had anxiety when I'd have to go to my children's School functions, interviews, etc... Just too many bad memories of school... But I struggled through life & a retail career... Then when I had a bout with depression issues, my doctor seemed to think I could also be suffering from ADD, put me on A low dose of Ritalin, tweeked it over a few months... Wow did it change my life... After being on the med for about two years, I could see how much better I functioned mentally, intellectually.... I went back to school Completed my grade 11 & 12, top of my class..... went on to become a Nurse at age 45...
