Feeling Lost, Worthless and Useless

My feelings, emotions and struggles are constantly invalidated by my own family (literally the only circle I thought I belong) They don't know about my depression. Or to be exact, they don't care. They acted like they care just to make them feel good about themselves. I tried to tell them, I gave them countless hints, none of them matters because my family doesn't care anyway. I'm just a substitute after all. A substitute when they couldn't do their "roles" as a child. But still, I'm not good enough. I'll never be good enough. No matter how hard I try. I'm just that 'lazy' daughter of the family. I'm just a burden. If only they know how much efforts it takes everyday just for me to get out of my bed, go to work, do house chores or simply to breathe. It all takes a toll on me. I wake up and go to bed with a ton of burden on my shoulders. I'm never relax nor happy. I'm not living. I just exist and somehow, I'm surviving, all alone.
