Showing a lot of the symptoms but have done all my life. Annoyed nobody else picked up on this when I was a younger girl. now I'm older it seems that I might have dyslexia.

If you are still in school you can ask there or go to the Doctor.
When I was in College my English teacher thought I was Dyslexic. I said 'Nope, I'm just bad at spelling!' and I was just bad at spelling. Moral of the story: It's hard for a lay person to tell the difference, so don't feel angry.

There are lots of tests online you could take, and then follow it up with a doctors appointment.

Or, if you're still at school or college you can go to a counsellor or the SEN department (special educational needs) and they should be able to tell you

the fact that you can spell dyslexia, I wouldn't bother

Your spelling seems fine. why get tested for something which does not exist?

Go to your doctor and ask him for a test .
