I assume that's a genuine question and that you're not trolling.
Opioids are a very different class of drugs than anti depressants (including medication to treat anxiety).
While people with mental issues may use opioids for self medication, no reasonable psychiatrist would ever prescribe such medication for psychological issues.
Oxy and their ilk were massively pushed by Purdue and their "colleagues" as a non-addictive pain relief if applied correctly.
They lied, of course, and that's where the US is now with the opioid crisis, since those drugs were massively over-prescribed.
It can't be mentioned enough that if you have serious mental issues then appropriate medication may be one of the pillars to help you out of the deepest circles of hell.
While it maybe a crutch (sometimes temporary, sometimes long term) it can be immensely helpful if properly prescribed and monitored and seriously be the difference between life and death.
Some medications used for mental health can be addictive, and some can have "discontinuation effects" (these are important and unpleasant but are not really addiction). The addictive medications are the benzodiazepines and the "z drugs" (zopiclone, zolpidem, etc (sleeping meds)).
I think mental health medication is good and useful, and I think SSRI / SNRI / NASA type meds are very good, but useful questions (for any medication) are "What happens if we do nothing?" and "what are the side effects of taking it, or stopping taking it?"
These medications are not linked to the opioid crisis. The causes for that are complex, but they include over-prescribing of strong opioids for mild pain over many years.
Antidepressants have nothing to do with opioids. Almost none of those who are still on the market even have the slightest addictive potential. In fact, even products which only had very minor such potential have been withdrawn, even though they were much milder than drugs on the market such as benzos or opioids.
Also note that opioids are depressants, though that is not an antonym for antidepressant.
