how to get through 21 semester hours?

i feel lonely sometimes.
i prayed in the bus and God told me He would be my fill, He would grow me. i know it's true, i know He hasn't left me and that everything happens for a reason. yet i have this pounding headache and a longing for something more. i wish to heal the earth, my little part. whatever little purpose i have. i wish to fulfill it well.
i know, dirty rags, yet i believe in God's goodness. this hits home with me:

Excerpt from "To Write Love on Her Arms"
by Jamie Tworkowski

...Don Miller says we're called to hold our hands against the wounds of a broken world, to stop the bleeding. I agree so greatly.
We often ask God to show up. We pray prayers of rescue. Perhaps God would ask us to be that rescue, to be His body, to move for things that matter. He is not invisible when we come alive. I might be simple but more and more, I believe God works in love, speaks in love, is revealed in our love.

i want to be alive. i want to be the visible tool which God may use at His free will. i want to do something. i don't want to stay passively watching the world crumble. i want to be the change i desire for the world. we often deny that we are a whole. we think of ourselves as parts-- the mind, the spirit, the body. but no, i think it's the whole. we have to fully love --mind, spirit, body-- and then will we be truly free. our parts have to be in accordance. our parts have to be submitted for a cause, a conviction. equally, we shouldn't be divided with humanity. i know we have our discrepancies, and of course, we would not agree with unethical things, i think i'm safe in assuming no one wants the discriminate murder of babies or a particular race... yet, there's something deeper. there is power when people have the conviction that world hunger should end and they unite despite differences to make a difference.
i am not entirely sure this ramble is going anywhere really. i just needed to get it off my chest.
