imo, trying to fix your MaDD solely by getting rid of the daydreaming is like trying to pull an arrow out of a chest wound without having any stitches or bandages (or trained medical professionals) on hand.
like yes the situation is not great and you probably shouldn't just leave it there forever but that is my coping mechanism and getting rid of it right now would be viscerally excruciating and without it my psyche will metaphorically bleed to death unless there are healthy solutions immediately available to patch it up and help it heal properly.
i think it's extremely important that when we discuss recovery from maladaptive addictions like MaDD, we keep in mind that such behaviors are typically filling in for something we DO desperately need in our lives, whether it be more/better platonic or romantic relationships, a more fulfilling pastime or path in life, a healthier family/living situation, a decent therapist, or even medication for other disorder(s) that may be reinforcing our excessive reliance on daydreaming.
may we all graduate from our maladaptiveness to one day become immersive (or casual!) daydreamers <3
