When I went to my T to deal with depression, she talked a lot about mindfulness and really encouraged me to give it a try. However, she focused less on the meditation aspect of it and more on the "state of being" that it emphasizes. The biggest thing I got from it was to be non-judgemental of myself, my feelings, my thoughts, and ultimately, other people.
I have tried meditation a few times but I haven't gotten into the habit of it yet. I think it's easier for people trying for the first time to start with 5 minutes and then work your way up to 15-20.
There is a website I found that has been really helpful for me:
Left Brain Buddha - the modern mindful life
I encourage you to check it out and read a lot of the postings on there. It's geared toward people who struggle with the concepts of meditation and mindfulness and for those who don't think they have enough time.
Good luck and just keep trying! Mindfulness is difficult when you start but even trying a little bit can make a big difference.
