Can't recommend it enough. It's frustrating at first, the mind will just not stop wandering to worries every 10 seconds, but almost always on cue, the guided meditation would remind me "is you're mind wandering? no big deal, bring your focus back to your breath."
Here's where I recommend starting - http://www.nytimes.com/well/guides/how-to-meditate
There are a few moments now where my mind will go entirely blank, and it's the most relaxing feeling in the world. I still get too excited when that happens to keep it sustained, but I can sense it starting to work.
It's really helpful to check in for a few minutes throughout the day as well. Take something in visually, observe a feeling, listen to what your body is telling you.
Sounds hippy-dippy, sure, and I'm not pretending to be a doctor or make medical recommendations, but for me, It Just Works (TM)
