amanda, what you write and describe is horrible. what you describe can bring tears to eyes which only read your words and haven't even seen, experienced the reality which you encounter.
you ask for advice. i think you already know that no one can really help you with this and maybe you just want to share something, so that you don't feel so alone with it.
there is a certain naivity in your posts and i hope you can see this as an advise and not an insult. naivity means, you somehow ask stupid questions:
It's not a crime to be innocent, these things we have not done
But you're not some little child, spring is past and gone
Well I know my craving heart and I've seen your vicious eyes
And I think we know the truth, both you and I
Don't flutter your lashes like a little girl
And ask me why it's such a cruel, cruel world, no
you go to places which overwhelm you and than you feel small and sad. you always take so much on your shoulders, which are not your problems, or wrongdoings. young people do that, but young people should also don't feel as involved as you do.
if you feel that you cannot cope with this, then leave. i already told you something like that before. you put yourself in situations which are maybe to much to take for you.
find your way without wanting to solve all problems of teh world, before you don't feel safe in yourselves and get some more self-consciousness. you won't get that in extreme situations, like you are in. what about a holiday? experience travelling and watch the wonderful world and nature instead of silly, cruel human behaviour.
and if you must, think of it as an energy recovering for yourself, a battery recharge, and then go again to help, if you think you must.
be aware that all decisions are your own descicions and that other people have other descicions to make and that your way is not the only right way to deal with the world. people who sacrifice more than they can, become bitter and look down at other people who don't sacrifice that much.
everything is all the time
the beauty and the horror
don't look just at one side
