For you to be dyslexic there MUST be a clear disparity between known intelligence vs. ability in reading, writing or both, there is NO such thing as “mild dyslexia” as that is just the new polite buzz words for being “below average” in one respect wile still being within the bands of being an “average” person.
e.g. if at 14 years old you have an IQ of 100 however your ability in e.g. writing only matches that of someone who has an IQ of 50 then there is clear disparity unlike someone who has an IQ of >75 in the same situation.
Taking the same 14 year old one would expect an average one to have a reading age equivalent to 14 year old, if that 14 year old has a reading age of 7 years old agene there is clear disparity indicating a problem rather than just being a little behind if they e.g. had a reading age of >10 years old.
I left school only able to write my name excluding my middle 2 names which I couldn’t spell & my address as long as I omitted the house name which agene I couldn’t spell, so really unless you post on forums with the aide of a well trained copy of e.g. MS Word to limit errata/duplicates/etc as well as to correct spelling, capitalisation etc or haven’t spent 20+ years after leaving school trying to learn how to as well as all the possible ways to hide it then really you aren’t dyslexic but you may just be a little behind your peers in some respects or may just even be average!
There was a time when I first really started to learn to write (at 30) with the aide of a PC that I use to post on forums as I wrote it totally uncorrected as I though why should I not, however I soon learned that the first thing people who can write do (adolescents & yanks being the worst) when they are wrong is sight your incorrect spelling & lack of punctuation etc as being why they are right especially when you are imparting technical information that they disagree with mainly to save face, but like I have always said to people the ability to read & write like age is NO guarantee of wisdom.
Anyway I know the above will/may sound a little arrogant or demeaning to some but that’s just tough like life sometimes or the hand you are dealt in it, what maters is how you get on with it.
