You are clearly an intelligent young woman, and your determination to finish school is something that should be supported by all of the adults in your life. If possible, go back to the school you were attending and talk with a counselor or the principal about your family’s circumstances – including your struggle with depression.

But a counselor should be able to help you to transfer if that becomes necessary.

Thank the donors warmly for their thoughtfulness and generosity, and say you already have all the things you need for the new baby.

(Warning: To avoid possible hurt feelings, do NOT include them in a yard sale.)
