I know it sounds gross and like a little kid thing, but I've always struggled with persistent oral hygiene.  This morning I woke up determined to brush my teeth, and yet I had an intrusive thought that caused a 15 minute episode of crying and after I just didn't want to do it anymore, and so I didn't. My mood largely affects my productiveness, but I really want to fix that.  How can I become more accustomed to brushing everyday and night without being affected by my mood?

Thanks &lt;3
