I can't even tell whether I'm faking laughter or not. I know when I'm faking a smile versus when I'm actually smiling; the prior feels forced. But when I laugh it's over-the-top, even if something isn't really funny, This is only to feel the enjoyment slip away within minutes. So it isn't forced, it just comes too easily and is so exaggerated that I don't trust that it's even genuine. It makes me sad to question my own laughter this way, but it's concerning to me.
I guess that it doesn't matter, really. The people around me think I'm happy. It's not like refraining from laughing would do any good. I don't feel dishonest for laughing, only confused. I bet I'd feel comfortable if you made me laugh.
