Feeling low when a hyperfixation ends

Hi everyone, I think I am noticing a pattern... when my latest hyperfixation starts to wain and there isn't a new one waiting, my depression seems to get a lot worse. The boredom is crushing and I can't get interested in doing anything at all even basic day-to-day stuff. Has anyone else had this experience? Any coping strategies anyone can suggest for me? Thanks so much.
