It’s also not a bad idea to seek professional help, if possible. Make a plan to get yourself going, with reasonable goals. As already stated, a desire must be there, if you’re doing it to appease others, this includes going as far as attending support groups, there is less chance of success. The person with the addiction has to want it and has to be ready for it. It takes some soul searching before an addiction is beat, there needs to be an understanding of how and why the addictions were developed in the first place.
If a person has a dual diagnosis then it’s exceedingly wise to get professional help. Many people who have clinical depression will turn to the object of addiction because it makes them feel better, and when the addiction is then developed and can be diagnosed, it’s a dual diagnosis (the first being the depression, the second being the addiction). A person may have a better chance of beating their addiction if they can get properly medicated for the primary diagnosis.
A support group or therapy at the same time is helpful because when the individual with the addiction begins to face some of the other problems that may have arisen during the addiction (e.g., relationship, financial) they’re going to need some help in dealing with those issues without turning back to the addiction, or even developing a new one. Those problems don’t miraculously vanish the moment a person starts dealing with an addiction.
When I write “you” I’m speaking generally, not personally.
