Opioid replacement therapy can help people control opioid use while developing new ways to cope and manage emotions, but ultimately developing new ways to cope with things like sadness and finding new things that bring joy into our life is how we manage a substance use disorder. People abuse drugs not only to avoid feeling negative emotions, but also as a means to experiencing positive emotions as well. I know I became very isolated when I was using drugs. Reaching out to others helps me not only address things like anger and sadness, but also is a way to experience happiness through conversation and laughter. I've been playing music for 15 years as well, it's not only a way that I can express negative emotions, I also get a lot of joy and sense of accomplishment from playing.
In terms of opioid replacement therapy, like suboxone or methadone, I think a major factor would be your extent of use. How much are you using at one time, and how much are you using in a day? How many days can you go without use? Do you go into physical withdrawal when you don't use? Are you engaging in risky or damaging behavior in order to get drugs?
If you aren't going into debilitating physical withdrawal symptoms and aren't engaging in risky or damaging behavior to get opioids, I think you'd be better off without them. ORT is mainly intended to reduce the damage associated with opioid use and serve as a stepping stone while the individual gets their life in control. If you can manage the withdrawal symptoms and the most damaging part of opioid use is the actual results of using opioids, I would think it'd be better to go without. Some people experience severe dopesickness that prevents them from functioning in society, doing things like going to work or being able to keep food in. The withdrawal symptoms and severe cravings also drive some people to do some extreme things in order to get drugs, things like pawning all your stuff to the point of homelessness or even trading sex for drugs or money to get drugs. ORT can help people resolve some of the chaos that is addiction by reducing or removing withdrawal symptoms and cravings. If cravings and withdrawal isn't preventing you from dealing with your problems and you are just struggling to deal with difficult emotions, I don't think ORT is for you.
It wouldn't hurt to talk to a substance use counselor or even calling up a local methadone clinic.
As far as dealing with the urge to use... making a list of both the positive and negative things that result from drug use can help you visualize and understand your behavior. Positive things might be something like feeling warm, happy and upbeat. Negative things might be having no money left as a result and feeling even worse after the drugs wear off. Many of the negative things will be resolved by quitting, the hard part is finding healthy ways of replacing the positive things. Things like exercise can help stimulate endorphins, which are natural chemicals in the body that resemble morphine. Going to recovery meetings, picking up new hobbies, and other social activities can be a good way to build self-esteem, laugh, and fight some of the feelings of loneliness.
In the beginning, it really does help to take things one day at a time. A bad day doesn't mean a bad life, tomorrow can always be better. Focus on things you can do to improve your day each day. Abstinence is just the beginning of recovery.
