feeling lonely

I feel alone... like No one cares what I do, where I am, or even just caring about me. I have like 2 friends that I can actually trust. I live with my father and little brother and I'm expected to do everything, I don't feel I should considering in only 16. I pick up after both of them, and I never have time to myself. I never just hang out with friends, and I never have. I don't go on dates... Nothing. I don't know how to feel about anything anymore, I just know I feel alone...
