Im in my 20s and Im barely able to read and spell properly

No joke, I was 18 before I could properly spell the word "bear" (always spelling it with an e). I'm 22 now, and I've found that Im having to double check the spelling of thousands of words. I've always struggled, but it was never properly diagnosed. Im going to an adult literacy program, and the teacher was shocked that Im in university, never noticed a problem in school, and has never been suggested tutoring. I'm 22 and I still spell colour like coller. I never noticed it until my first year of university but it makes sense now. I would copy my notes from my classmates because I could never keep up. I was always decent in math so I never really thought about it. I was able to get accepted into university with a 82% high school gpa.<br><br>Im worried this is going to hold me back, especially with my career aspirations. I'm worried my teachers will think less of me, or my grades will slip. I've already told one of my professors and he just brushed it off and said "its not a problem, everyone has their things". I dont know how much time it will take to improve. I would like to think I dont have a disability but its so obvious to me now when I read my own writing. I dont even think I would be able to pass a drivers test written exam. I'm never going to be able to sound smart or well read. I'm so embarrassed by this. It makes sense why I've always liked numbers so much. I got a 98 in statistics because it was all problem solving. I would just like some assurance that it may not hold me back too much.
