Meditation has been a weird journey for me. Took a few tries to find something I'd stick with, and so far, it has made it easier to stop thinking about some things. Basically, meditation for me is a time to detach from my thoughts. Give myself something to concentrate on (drums for me), and do that for 20 minutes daily, and when the mind wanders, just go back to the sounds. And after a while, it is like your mind gets more used to doing that - I don't dwell nearly as much. It isn't perfect, but better.
Some folks find mediation makes them feel worse, depending on the technique and what is going on inside the person's head. Some of the repeated thoughts can happen in depression and anxiety. Meditation combined with either illness can be weird - some folks get a lot out of it, especially if they have comparatively mild symptoms, and some find it makes it go awry, for lack of a better description. Also, for females, hormones can cause sticky thoughts sometimes. This sort of thing might make medication a better first helping choice than meditation.
