Being a little anxious and meditation don't really go to well together, but I still do it all the time. I've actually done it at work before and achieved a really nice state of relaxation even in a room full of people I hardly know. For me, it doesn't take sitting in the lotus position or listening to new age music (although that shit's amazing) to achieve the state - it takes absolutely nothing. But it's really hard to keep free floating thoughts away.
Basically (for the times that have worked really well), there's no exact routine for me. It doesn't even have to be dark, just not excessively bright. I just sit down, back against the wall or a chair so I don't collapse into a deep sleep, and just BE. I seriously just sink into myself and gently stop my thoughts. If you try too hard NOT to think, you end up overthinking the fact that you're supposed to be not thinking and whatnot, so it's always best to leave a little room for the inevitable thought to creep in every few minutes or so... and just let it come and go on it's own. It's when you start giving focus to that thought that it really becomes a problem and invades your inner peace!
What's best is to just read up on it and experiment. Some things work for you, some things won't. I wouldn't suggest laying flat or going somewhere TOO comfortable, because you'll just fall asleep. Even for somebody with insomnia like myself, when you start meditating... that's the biggest temptation. Like finally realizing your body really has the power to fully relax. You want to use that to your waking benefit, not just an amazing way to fall asleep (although it works great for both!).
The only warning I have is to not take meditation too literally, or you'll get discouraged. Because no, it won't bring spiritual enlightenment or anything the Buddhism religion promises, unfortunately (lol, that's religion for ya)! However if you're looking for relaxation... there's no wrong way to meditate. It's all about making yourself feel relaxed and at a nice, balanced, chilled-out state. Hell, I've even gotten chills from meditating. Just have fun with it, and don't worry so much about how to do it, just go by how you feel while you're doing it. There's still no wrong way to do it, so... just do it. Good luck dude
