I can't breathe

I'm so so so so stressed.  I feel like I need to cry, but every time I get close I have to stop because I'm around people.  I don't have any reason to be so goddamn upset.  It's my senior year of high school, I've been accepted to five schools so far, I have friends and family that love me.  I play three instruments that I love, I sing, I knit...all these things give me joy.  And I still feel like I need to bleed out all my fears and sadness.  Fuuuuck.  I'm just a shit storm recently. Argh.
