What am I

Tired. Frustrated. Confused.

I've been always keeping things to myself. I never wanted to admit that I'm not capable of things. Always don't want them to worry about me and push myself to the limits. But today, that ego ate me up from the inside.

I easily frustrated over little things, and even lashed out on someone whom I love. Hurting her feelings and act as if I don't care. I seriously don't know what I am that moment. Words thrown out unlike myself, emotional unstable and everything.

I really confused now, I don't know what to do next.
I really don't know who I am now,

I've lost my way.
