I Wanna Smoke Weed

Okay I know this sounds silly but I really need an outsiders perspective on this. So I have really bad depression, anxiety, and ptsd. I also have terrible back pain from a spinal reconstruction surgery almost a year ago. I've been on so many pills to help with these (valium, percocet, xanax, etc.) A lot of highly addictive pills. I don't like being on such strong pills for everything and hear smoking weed can help, at least with anxiety and muscle pain. I'd prefer to take a more natural way of coping rather than addictive pills, but my fiancé hates weed. His dad is an asshole and my fiancé associates him with weed. He's tried it before and says I'm not missing out, I have nothing to go off of because I've never tried it in my life. He just doesn't like it and has said he wouldn't want me to. Idk what to do.
