Sometimes you just need to take a deep breath
I find if I take on too much for too long, I get a familiar feeling. It's kind of unpleasant, like a crushing sensation. It's a feeling of always being in a hurry, of not having enough time, of being behind.
I've got that right now, but I'm getting better at dealing with it.
This helps, as does putting on some relaxing music, taking a deep breath, and looking at the sky.
What do you do when you get stressed?
