It's your own weird, it's too common with both entees and endees to be related to falling on the spectrum. The way you write might be more related to being on the spectrum; same with the cycle of obsessively creating and destroying your work. If you're having really productive periods you should ask someone to 'steal' some of it from you to preserve it, it might have value beyond just expressing in the moment.
I write rambly barely rhyming poetry a lot, usually just reflections of social/political/personal issues that are often too abstract to really make much sense. More recently I've started writing down ciphers I come up with in response to songs I listen to and then picking apart the rhyming strategy.
