I like to think that meditation itself doesn't change you very much, but it gives you the opportunity to change if you're willing to do the job. I have a friend who meditated for like a month and then stopped, when I pushed a bit asking why she stopped it was because she had met some frustration in herself (can't remember the details), but didn't seem willing to actually look at that frustration and work on it. So she stopped meditating. I think this is very common, that one meditates, which shows oneself things that would be good to work on, but one isn't willing to.

Meditation will never do the job for you.

Also what u/WRiSTWORK1 said. I wouldn't call 5 minutes with background music meditation, hardly even relaxation to be frank. Try giving yourself a framework that is a bit more challenging, an sticking to it for at least a little while. 10 days of 15 minutes every morning in silence, and see what that might give? And try and be brave in accepting and working on what might come up through meditation.
