I wish I could go out at night and look at the sky. I live in a city so it's not feasible. I'd be uncomfortable outside here and I doubt I could see many stars, if any.
Thinking about and admiring the universe is also my main therapy as well. Just thinking about how beautiful and mysterious everything is, and the insignificance is actually comforting. But also, I see everything as very significant at the same time, because it all is so fascinating, life itself is fascinating and how it evolves and changes. And to think that life on this earth will eventually be gone and changed, makes it more necessary to appreciate it. I like to think on that saying, that we are the universe experiencing itself, it really is wonderful.
I honestly think about it all the time, can't stop. It's comforting and awe-inspiring. It also helps with depression and anxiety for me, because I can see "reality" more and what really matters. Although, other people tend to think I'm strange and not focusing on what I should, apparently I'm not focusing on "reality" enough - their reality being acting normal, getting a job and conforming, I can't quite do that though, because I cannot forget about the true reality. We're on a floating rock in the universe, there is not meaning as far as we can tell, so I don't see the point in trying to distract myself from it and conform to our made-up society. I don't want to be distracted from the universe.
Hope I don't sound odd, but I really liked your post because I'm similar.
