Indica is best for healing, it’s important that you sleep enough, even if it’s 10 hours, if your body needs it then give in to it. You heal fastest during sleep. Came across this strain yesterday, that’ll have you sorted for THC: https://www.zamnesia.nl/original-sensible-seeds/5185-grandaddy-black-feminized.html
Though I’m sure some good people here can hook you up with something better maybe.
And I think growing different strains and mixing them is probably the best way to go!
Have a speedy recovery, good vibes to you!
