Well, many people are dependent on things like exercise or their hobbies to help them feel good and balanced. I would not be happy and content without doing the things I enjoy in my life. Do you just sit around all day doing little else? If there is no negative associated with your meditation, why to worry about it? If you do worry, change your routine around a bit. I think that trying to change how we feel if it's negative is a good and healing thing rather than not doing anything just suffering. You have been through so much since you got sober and you have found a way to ground yourself that works well -- I would not question it.
