Rambling: Theater

Ever scince the 7th grade I have had a passion for theater. Ive done tons of stuff with my church and ive been in drama classes all throughout high school. But so far I have only been in one school production "Our Town" last fall. (ive also tried out for two musicals but didnt make the cut) But im going into my senior year and i feel like im starting at the botom. When i get out of collage i want to become a drama teacher. Its like i feel it in my heart that its what i love. But yet i feel kind of useless with the whole thing. I dont know wwhat my problem is but i seem kinda upset about it. like i failed but i know i can still make up for time lost.
