Has anyone else struggled with fear/anxiety when trying to reduce opioid use?

I've been gradually trying to lower my opioid use by exploring non-opioid alternatives and pacing techniques, but the mental side of it has been way harder than I anticipated. I'm constantly obsessing over what could work and if I can manage my pain.

Has anyone tried an alternative, such as trigger-point injections (or similar procedures) to manage the pain and overall mental perspective during the process?

Thanks in advance.
