If you know someone who seems to be suffering from depression, encourage them to seek help. Self-medicating will only make the problem worse. And if someone you love is depressed and addicted, get involved. Start by having a conversation about the problem. This won’t likely solve everything, but it’s a step in the right direction. Next, encourage that person to get help from a rehab that specializes in this co-occurring disorder.
Depression and addiction are both dangerous problems that are not likely to go away on their own. Get involved when you can and try to help the people you love.
