Cbd is non psychoactive so I would look for strains high in cbd.
Personally ,as much as I love marijuana its almost the worst thing that's ever happened to me. I self medicate and the thc, after long enough almost always spirals me into a mania psychosis that seems to get worse every time.
If you do your research most studies have determined that it worsens this condition. That is why bipolar and schizophrenia aren't qualifying conditions for medicinal states.
I'm sure there are the few out there that it helps with. I know how much it helped with my sleep and depression and ibs. And I'm sure ill go down that road again but I have to stay away from it at the moment.

Favorite is blue dream.
