Does anyone feel the need to constantly write things down?

It's a disorder called hypergraphia.

I can't have a conversation with someone unless I write everything down. This is why I much prefer meeting over the phone vs. in person. I get soooo much anxiety when I have to make eye contact.

It's causing me so many problems. I can't get anything started unless I type an elaborate summary of the task ahead, throw in links to helpful resources, and over analyze the dickens out of it.

HELP!
