i have about 10 handwritings i could detect up until now and variations on these.
some are very different in size and right- or left-justified (hope it is the right word) and just "style".
i am right-handed, but i have left handed writing as well.
figured out, that i have been left-handed as child as in therapy with modelling paste i am left-handed and a toy cat where i have early routine touching the face and scrubbing the nose movement is left-handed and sucked left thumb as child.
i have periods i write a lot on paper, but periods i cannot write (no ability, also on PC).
so i have more "writings" from age i cannot write (times i try writing but no ability also on PC).
i am not diagnosed DID/DDNos but confirmed having "strong dissociative disorder". whatever it means.
how many different handwritings you have?
