You may think that your overworking, drinking or drug use, love addiction, or your (fill in the blank) is your problem. And let's be clear, you need to do something about that thing.

We choose maladaptive behaviors to avoid dealing with our core issues, which are usually related to unmet needs and traumas in childhood. My original core issue was childhood emotional neglect and abandonment.
Drugs allowed me to live in a world where I felt that I belonged and was cared for, finally. When sexual assault and physical abuse were layered onto the original core issue, I had to use more drugs to further dissociate from my combined traumas.
I thought that was the solution, until it wasn't. Recovery from substance use helped a lot, but residual trauma and still-unresolved core issues led me to become a workaholic.
