People call me slow but I have started to get very defensive

Well, one thing that stands out is you don't say a word about working on your issues. If you consistently make mistakes that's going to repeatedly affect your life and frustrate others around you, and lashing out at others will have limited success.

Since you asked, I'll put this quite bluntly. The person you laughed at has a recognized and genetically influenced learning disorder... so what's your excuse?

I can often be slow, make mistakes and don’t think as quickly as other people. As a result I have been called slow, dosy and some folk have even ‘half jokingly’ implied that I lack intelligence. My grandma before she passed away said that I will never have intelligence like my mum. I asked how do you know who is more intelligent. She said that she could tell as she brought both my mum and me up that it is easy to spot intelligent children by the things they do/how they interact etc. I felt like pointing out how she hadn’t achieved much other than give birth but it would have just ended up a tit for tat argument.

As a result I feel very defensive to the point where I will look for weaknesses in the people who insult/say these things about me. One of those who commented has dyslexia and needed extra time in exams /different coloured paper etc( I certainly didn’t need this and got through my academics with no adjustments). There is nothing wrong with either (please don’t think I have anything against cognitive issues) but if I am called out on my weaknesses why is their weakness protected by a label? For example if I laughed at them for being dyslexic how is that different from me being called thick, slow?

Everyone is different and has their own weaknesses at the end of the day whether they have a label for it or not.

Have you looked into dyspraxia at all?
It affects slow processing and can make someone seem clumsy and uncoordinated (I have it myself).
