Dealing with the emotional hell that comes after a migraine

Hi everyone,
I'm have been diagnosed with chronic migraines a few years back and while I feel like I have somewhat figured out how to live with them, there is still a lot of stuff to learn.
I'm writing this while I'm in the postdrome phase of my most recent migraine, so I wanna apologize in advance for any incoherence in my thoughts.
How exactly do you deal with the postdrome guilt of a migraine?

For me, that state usually involves being incredibly depressed, overwhelmed and just wanting to isolate myself while even the thought of doing anything conventionally considered productive or social just feels like it would put me on the verge of breaking down.
I usually try and just take it easy for the rest of that day (if possible, as it may not be possible to do so at work) but I can't help but feel defeated and guilty whenever these days do happen... Worst of all, knowing that there is another one coming feels so cruel.

Does anyone have any advice on how to better deal with the postdrome?
