I'm the sole caregiver for 3 disabled seniors, one's my husband, and it's my whole life.  Facebook's my only outlet, where I complain, joke around, write very short stories, and give some political input.  I suspect many get annoyed with me, although I picked up over 300 friends quickly.  I'm very sad to feel that I have to reign myself in to appease undesignated facebook police, (my friends).  None of them have the sheltered, unexciting life I have, but they're still very opinionated and unempathetic.  I've started a book off Facebook called Fair Weather Friends and Other Silent Killers....might even name names in it.
