Seems to me i remember you saying in some post that you have been dx'ed on the aspergers spectrum. I'm thinking that might tie into that. Think my ex struggled all his life with un dx'ed aspergers & he couldnt handle a paint brush for painting a color wheel in an interior design class we took...he blamed it on never being taught how to paint...well i hadn't either but had no problem.....i do think it can show up through things like that.
Don't be so hard on yourself we all have limitations in one thing or another
