You need to change your perception on opioids asap. Some people just fair better in life on opioids, they suffer less and even live more enchanting lives even when facing against the odds of societal stigma and family disapproval. Imagine just for a moment, if you purified yourself of all that guilt by proxy. There's no reason to feel guilt for using opioids, you are pursuing what feels right to you, you are in the pursuit of happiness just like everyone else. If you aren't an over the top junkie who's a living hyperbole for junkie behaviors then you should literally have nothing to feel guilty about. The people "hurt" by your use need a perspective change. Rehab is obviously a scam and a waste of time for you. If your family harbors a lot of distrust and disappointment for you for trying to be happy, then ask them why the fuck did they choose to procreate if they were never willing to acknowledge the risks of bringing a human to full-term; suicide, drug abuse, starvation, horrific accidents, illness, etc. are ALL possibilities that you must acknowledge before procreating, and for them to make you feel such a way for trying to sift through the bullshit and create happiness the best way you know how then they are inherently flawed.
