I don't think that anyone can tell you what meditation is right for you. It's sort of like someone telling you what your favorite food is. Without knowing you, they couldn't really tell you this unless it's a guess.
You know yourself best. You would know, or be able to find out, which type of meditation is best for you.
The best way to do this is to just try out a few different types, and to see which one feels best for you.
I think the most important thing, at least for beginners, is to find one that you can actually do on a daily basis or at least consistently, otherwise, if you are not consistent with your meditation practice, you may end up not really doing it enough to actually see the benefits. Both not having a consistent meditation practice and not seeing the results could just lead you to not meditating at all eventually.
I don't think you should be emotionless. I think that, in a way, you shouldn't be anything, you should just be there in that moment.
By that, I mean, you should just let what ever emotion that comes up be, and just watch it and understand it. Same as thoughts, you shouldn't be fighting your thoughts during meditation, you should just be watching them, not trying to alter them or control them, just letting them be until they eventually drift off.
It's the ability to be in the here and the now, and to not focus on past events or future possibles, things which cause stress, anxiety, and often depression.
I was thinking about my life, and how I got to where I am right, for better and for worse.
I thought about if where I am now is where I wanted my self to be when I thought about this 5 years ago.
It's a difficult question to answer, really. Though I may not be living the life I always wanted, parts of who I am are due to the life that I did live, and at least some of these parts - I like.
Or course, I can't know who I would have been if I had lived the life I wanted, maybe I would have loved all of me, maybe not.
So it's sort of bittersweet in a way. The main thing is to look ahead and be excited for what the future may hold, because it can hold anything.
