Conventional recommendation is to go see a talk therapist, but I have never really bought into it. Other thing I have seen recommended is LSD/DMT which I would have tried by now if I wasn’t married, it seems like too bug of a risk that LSD/DMT will alter my psyche in such a way that ruins my marriage which is not fair to my partner.
Best I have found is detaching from society, back country camping, no technology. But I don’t want to become a hermit in the woods to just be able to sleep regularly.
