Feeling Overwhelmed and Pushing People Away

My parents have officially told me that I am overwhelming them. I am constantly overwhelmed by myself, and have no idea why I get so upset all the time. But my mom turning around and yelling that she does get being overwhelmed all the time because it is me who overwhelms her constantly. I fear that no matter how hard I try to shut up and close up. I will only ever continue to push people away and make people despise me. I have spent my entire life even as a child trying to be quiet. Keep to myself. And over all just leave people alone. But I feel awful when I stay quiet. It has gotten to a point where everyone tells me I just overwhelm them. I am trying my best. I move out on my own in January. I am sure everyone will ghost me afterwards. I am terrified. Living on my own always fails. But ah..it's gotten to a point where I am being asked to leave my job because I cry to much. This is like the third time this has happened. I am trying so hard to keep myself together. But I am failing horribly at being a functioning member of society. I also can't afford to get help or get on insurance as I already live paycheck to paycheck. I am filled with dread but trying so hard to get up and keep going everyday. I promise.
