Type of herb to help with anxiety for opiate recoverer

hey guys i smoked weed but it always made me super anxious and id worry about the weirdest sh** and just never could enjoy it the way other people seemed to.
sadly for me pain killers made me feel great i was very social and relaxed.
i know how bad pain killers are and im just wondering if there was a strain to make me calm and social that i could use to make the withdrawals better. i live in CO so i can get most strains i know weed makes mos feel calm and social but maybe someone has experience with what im talking about nothing too strong that makes me feel outta my head and anxious just a nice easy lift.

heavy Indica.......
