Answer on this is very easy. When you think that you have many problems, just relax, breathe deeply and, then think on something positive, do not let problems to get into your head again, so just continue same as before. Try also with sport or do something what you love. That can help for sure. At least I think so.
I don't know if there is any intelligent life out there, but I think there probably is some kind of life elsewhere in the universe. It could be some kind of bacteria or plant life but probably some kind of life.
