I love weed but it gives me depersonalization/derealization

As the title says, I appreciate cannabis and everything about it. The issue is, I always seem to get depersonalization/derealization the day after...which has even lasted for weeks before.

I really want to be able to consume MMJ as it is really unlike anything else in life and it brings me limitless joy under its effects. In addition it really helps out my depression/ADHD/chronic pain.

Do any of you have some input on what I could/should do?
