They certainly do.
I had an epiphany two days ago, made plans and started working on them. I knew there was a lot to do but I was motivated and felt like I could do it. Today was dedicated to being productive at work; instead I lost the day to a meltdown due to frustration with a person, something not completely turning out as I hoped it would which then quickly spiraled into the philosophy of uncertainty and my inability to handle it, then some more frustration with another person, and as usual, elaborate frustration and disappointment with myself.
I then wrote a post (which I never posted) revolving around said frustration et al and my new plan of going on a search for a nice cozy lake to drown myself in thoroughly and finally. Instead, I took a nap and now I'm procrastinating because I've lost so much time already.
