lng15, I am glad you wrote this post.
I also believe saving can become an addiction. When it becomes obsessive, it's definitely not healthy. IMO, the addiction is almost always the result of a deeper problem. In order to cure the addiction, that deeper problem needs to be addressed.
I, myself, have been struggling with obsessive saving for the last 1.5 year. Like you, it's hard for me to justify about any expense and I spend way too much energy trying to maximize my income, minimize my expenses, work on my networth, etc. For some reason, this brings me a sense of security and makes me feel good. While the frugal lifestyle is a core value I have and I want to keep, I can now admit that it is exaggerated and, at a certain point, unhealthy.
I've also been following a therapy for the past months (for this and other issues) which has helped me a lot. I can only recommend you find a professional to help you with this. It's still hard for me to justify the price (100 CAD/hour) for a meeting, but I can ensure that it's worth it.
Don't hesitate if you need anything else. Feel free to contact me in PM as well.
