Lost

I feel a bit lost.
I feel I don't know myself anymore. I used to be described as a good in school, organized girl. A little quiet, talking to low and shy perhaps but always there, no skipping class, attentivly listening, good grades. What happened to that girl?
What happened to the orderliness and structure? What happened to the once considered good girl?

I feel I lost her long ago.
I want to become miss responsability again.
Not necesarily weridly-quiet-shy girl, but the one considered to be one of the good ones.
Though I can't say I was a wonder of structure then either. Always doing homework and studying for tests last minuit. But I paid attention in class. No problem with focusing.
What happened?

Maybe it decreased with my diminishing faith in the future..that happened in my junior high and highschool years.
My diminishing faith in myself and my future...

I want to regain it. I want to believe. I want to strengthen and develop in a good sence, without taking any steps backwards or dissappointments.
Nice normal harmonious pace. Building a fundation. Firmly set in reality.
I want to feel good with myself.
To be happy.
Secure in myself and my abilities.

But how and where to start?
