Depression is eating me up. I cry all the time. I can't sleep. I feel worthless and hopeless. I might give up soon. I can't do this?

Never give up! I recommend you talk to a therapist, and sometimes taking anti-depressant meds really can help with the crying, sleeplessness, and all those thoughts going thru your head.Sometimes it takes an outsider to help you see it from another perspective; cognitive behavior therapy helps you do just that. Please find someone experienced and have a talk-there is always hope, don't stop believing.
