I Hide My Emotions Behind Humor

I think I've become a master at doing so. I am at a place where I would rather not talk about anything pain related. I have tried therapy for a short period of time, but it's not for me.
I just like many on here have a painful past. It's a past that has bittersweet memories. The bitter I can't forget, but I would rather not talk about it or share it with anyone. Maybe I am living in a pretense world, one where I hide my feelings with humor and smiles. It's my life and that's the way I chose to live it, sometimes even temporary happiness is all one needs to live each day.
