over my head

I've been in a bad mood for a while.
By a while, I dont mean a few days, or weeks, but months, months and months and months.
A few weeks ago I almost lost it, becasue I hold back how I feel, like when all I want to do is scream or cry( you know when you dont let your emotions take control of you, and one day you just blow up? Yeah..)
After fourth period, I ran into someone Im friends with, and figured would be there for me, so when they asked me how I was, I immediatly started tearing up; they didnt even try and comfort me. It flet like a slap in the face, and pretty much shut me up.
Needless to stay, I didnt bother talking about it with anyone else.
