I feel worthless

I feel as if nobody cares for me, nobody wants me in their life, no one is actually afraid of losing me, absolutely no one. Environment of my home is also very depressing and negative. I am dying slowly. Their is a boy I dated, he loved me alot but then one day we had a huge fight and afrer that he decided to break up with me. Later on, when I asked him to give me a chance, to be with me he simply said he don't love me anymore, he cares for me but he will not be able to love me. Later he asked me to be with him as friend and not leaving him even if he made a new girlfriend. I felt shattered. Right now, somewhere he knows I need him, I even called him right now but he was like I need my space I Am a little upset today. He is with his best friend. Enjoying, laughing. Having his time. But what about me, I literally have no one who can understand me who can say that don't worry, I am with you. No one values me. These thoughts and incidents are killing me inside.
