I think we as people look to others too much. Instead of relying on ourselves to make us happy we count on other people to do it. And then, when those other people disappear for whatever reason, our lives are destroyed and we're plunged into depression. We need to start looking to ourselves for happiness. If you can make yourself happy then no one can ever take that from you.
I am an amazingly good liar. I can, for example, confidently say that I don’t like anyone with a straight face, or swallow a laugh without making a weird face. I can purposely make my smile reach my eyes, so it actually looks like a real smile. It probably seems like a great thing, but after a while it’s hard to accept the fact that no one knows what you’re hiding - not because they don’t care &/ notice it, but because you lie too well.
