Rachel, I definitely understand that it can be tough to support yourself as a college student these days. We can definitely help you with whatever you need to do on your account. I think I found your account, but want to make sure. Are you sponsoring Obama in Rwanda?
It sounds like you definitely have the heart if not the funds. We do have a volunteer program in which you would write to a child whose sponsor is unable to send the encouraging letters. There would be no financial commitment - just the commitment to write at least three letters each year. Please let me know if you would be interested in this option.
