This article lists 5 guided meditations that are on YouTube that are rated highly. I haven't tried all of them myself.

If you search on YouTube, there are thousands of guided meditations. You kind of just have to look until you find ones that you like.

I respond well to certain types of meditation "exercises" and not so well to others. I like breathing-focused ones and sleep ones and "Leaf on a Stream" ones to name a few.

I think that it's easier to use guided meditations when you first start. I have only started doing meditation again after several years of not doing it. I find that if I like a meditation, and I make it a routine, that the benefit from it increases with time.

It's sort of like exercise or most habits in that respect. I was surprised to find how my mind becomes "trained" to respond to the guided meditations after using them for a while.

If using the meditation leads you to relax or stop thinking about something that's bothering you or to go to sleep, pretty soon your body and brain will start to associate that particular meditation with what usually happens when you do it. (I seem to be stuck with a sleep one at the moment that I'm kind of tired of, but it works so well that I guess I'll stick with it.)

I try to kind of just use my judgment about the guided meditations I choose from YouTube. Sometimes I really don't like the content of the meditation itself or I don't like the person's voice, so I won't use that meditation.

If you decide you want to practice meditation and you decide you'd like to try it with a group of people, you'll probably find Meetup groups and other free types of meditation groups near where you live.
