Funny distractions for big sad??

Depression and PTSD have been strong the last few days, and I'm struggling really hard with some things. My period is also in a few days, so I'm extra sensitive and want to cry every five minutes. But I don't want my boyfriend to know how bad I'm doing rn so I'm trying my best to not cry.

What are funny things I can do/watch/etc to keep my mind from going to these places
