I'd recommend seeking out a therapist if it causes you distress, specifically one with some clinical interest in psychedelics if possible (keywords include 'integration therapy'). Know that while there's still a lot to learn about HPPD, you are not alone, and in a lot of cases it can be managed. It's mostly a question of recognizing your triggers and developing tools to work through them (so if stress is a trigger, stress reduction techniques; abstinence from cannabis or other drugs if that's a trigger (pretty common), etc.)

Some folks just kinda roll with it, but there is stuff you can do to help manage.
