I was also one of those who in school was told that I could be anything that I wanted to be......ah ha, the limitations showed up & I wasn't even dealing with mental health issues before I was 40.

Things like my mind couldn't wrap itself around some of the chemistry things in high school, & calculus was something I just got through so I could accomplish my minor in Computer Science. I initially chose to be a music major with my flute.....but there again...even with practicing 8 hours a day....I didn't have the internal talent it took for it to just flow out of me.

Basically we can do anything we want within the limitations of our mental & physical capacities.....you will learn as you get older what you are good at & those are the things that you will follow & your goals will come from what you find you are good at.

Some people know they are good at things when they are as young as you are....others, it takes years of searching. It's good it works this way otherwise so many people would end up in the glamorous sounding jobs or the ones with the high paying income who weren't capable of performing.

Take time & just be aware of what you are really interested in & what you are good at as you go through school.

I also would suggest that you get help with the things that can be obstacles such as the OCD, or the dyslexia. I am sure your parents would be glad to get all the help possible so that you will be more able to succeed in school & in a career.

BTW, I went from getting an AA in music to getting a BS in Accounting Information Systems/Computer Science & a 15 year career as an aerospace firmware design engineer......never would have ever dreamed that would have been my career when I was growing up. Sometimes things just fall in place because we find the things we are good at & we are interested in along the way. I also had the difficulty in that I had to forge my own way through college as none of my family had ever gone to college or been a professional of any kind. It's true, we can be anything we are capable of being which we find out with age & with the classes we take & the grades we get.....which is why it's important to be able to take control of those things that can get in our way of success.

Best wishes on your future
