I feel like I'm just drowning...

Sometimes I just cant go on... my family and husband just put me down every single day. I'm not a good wife I'm not a good mother.. I'm stupid I'm fat I'm worthless... I stay strong for my kids but sometimes I feel like I cant breath. Why cant they see me hurting. I dont feel or look the same anymore. I pray every day so I can stay strong so i can find my peace again but i dont see it.
