Hi Nats For me, meditation doesn't always have to be of the sitting still, eyes closed type. There is a walking meditation, which I try and remember to do when I can. Mine's customised a bit, to allow for time and practicality!
Basically as I walk I try and focus on my surroundings, nature, sounds, the weather etc. Don't force your thoughts, just let yourself appreciate what's around you. Try and see things for what they are, without imposing your values and judgements. It takes practice, but it's strangely calming. It allows you to take a break from all the stuff clattering through your mind.
I try and be mindful in mundane situations. I read once about considering an object that has come to you, and thinking about the journey it made to get there. For example, a piece of clothing from overseas. If you think about all the stages it's passed through, all the people who've handled it, out their living their lives, it's an interesting feeling. It sounds like all this thinking will over complicate things. But in my experience it's the opposite. It breaks things down into their simplest forms, clears away all the drama and clutter.
I think I'd be more inclined to start with thinking of practicing mindfulness each day, as opposed to some kind of relaxation. When you're really stressed but telling yourself to relax, that in itself can put pressure on you. What if you can't relax, are you relaxing in the right way etc.
Being mindful can, in itself, be relaxing. If you're in the here and now, focusing on what you're doing, trying not to be distracted, you will hopefully feel a sense of calm. Your worries and cares won't disappear, but they don't get to be centre stage. Maybe decide that each day you will carry out a task/job being as mindful as you can. It can be as simple as making a cup of tea. Really focus on what you are doing - and only what you are doing.
What you're looking to avoid is that feeling that you get when driving a familiar route. You suddenly think oh god, I don't remember driving the last few minutes. I suppose the metaphor is that you want to enjoy the journey, not just reach the destination.
I don't know if the above makes sense or is useful to you. I found it all a bit wacky at first. But the more you do it, the more it makes sense.
