Stress Center Peer Support

Just about nothing could make me feel at ease. Why is it that I just feel like a stump that people can sit on and have a good conversation with yet I am just rotting inside?? Do people not see my face? Can they not see I am slowing losing hope in life??!I feel as if nothing could be worth trying, nothing achievable and nothing worth achieving. It's all a void that if filled, would be filled with sadness. I hate this feeling yet I know what I must do - Keeping doing. It will pass but I don't know why I feel so meaningless right now! Must I become comfortable with this sadness and work with it unitl I feel better? Must I accept it? I just want to feel me!!
Sorry, i just need to vent during this hard time. Anyone suggest any comforting books on depression or meaning in life??
