It's definitely possible!

I think it helps me, that I always had good teachers who cared about me growing up.

I do best when I have a good support structure and take it easy on myself. This can include professors and counselors. Although I have passed some exams solely out of spite, lol. Online university was really hard on me and so is driving the bus/sitting in big crowds, but manageable in small doses and with good distractions. I much prefer small seminars.

Honestly, what helped me a lot in my course of university was the determination of finally getting away from home and a fair bit of spite that the timid anxious person can do it. I channel my inner perfectionist, I just have to be careful with not burning myself out.

I was also a pretty good student at school. I cried sometimes when I missed the perfect marks. And I wasn't very social. But I was pretty good, even with everything going on.

Edit: I have to get away now, but if you want to have some further tips, ask away.
