*You feel like you simply cannot do anything right.
*You do not feel needed, and maybe not even loved.
*You feel like people wouldn't miss if you if you disappeared, or that they would get over your departure quickly.
*You feel empty inside--like something huge is missing but you cannot pinpoint it.
*You feel like your best will never be good enough because YOU are not good enough.
*You feel like nobody is genuinely interested in you and what you have to offer (though you may feel that you don't have much to offer)
