Don't really know if I should dive back in or not or WHEN

I had a few shares of this last week before it dove way further than I thought it was going to and I jumped ship when it bounced back up and I broke even.
NOOB move no doubt blah blah.
I am still "sort of" hypnotized by the whole thing...
My "plan" was to wait until it went LOWER and buy back in...
I guess I may still do that but have a SERIOUS case of FOMO...

I suppose everyone more or less feels like this.
