The answer is it depends. I have a severe case but was lucky enough to have a teacher that taught me skills to work around my version of dyslexia. I also had a friend that raised in a different part of the country where instead of getting the help he needed.

They just stuck him in classes with kids that had intellectual disabilities and just gave up on him. I was able to finished collage and got a job in tech. he dropped out after 2 semesters and became a truck driver. Honestly of the two of us. I’m more lazy than he is but he never got the skills.

To comment on not trying new things. That may have more to do with the Inferiority complex that comes with not being to property communicate your ideas. It makes you feel like everyone will see that you are stupid (even if that is not the case but its how you see yourself sometimes). It makes it hard show yourself as a beginner when trying new things. It brings back all that trauma of others judging your intelligence growing up.
