Handwriting change

I journal quite a bit and have for a while off and on (not online to be specific, merely a notebook and pen).

I had stopped since being back at work/covid restrictions eased off, and picked it up again this year around March.

I used to write very slow, in lowercase, rounded and large… however all of a sudden (almost quite literally a day apart) I must’ve started and lost track or didn’t notice that I now write fast/frantic almost, all in capitals, squared and small.

I have done a bit of research on the net, has anyone else had this experience? And if so this sudden and drastic?

Thanks x
