Anxious, sad, alone

Hi guys, first time posting. I am really confused about my life situation and struggling about it all. I am trying my best to recover from some very difficult abuse from about 6 years back. My family had done everything they could to help, and I escaped where I was and came back to them. I’m older and I live w my parents and sister. They are struggling with ptsd, anxiety and depression as a result of what we all went through. I have so much anxiety in the morning, daily. And I want to give up. I’m frustrated and angry that everyone is sick and I’m sick (I am also chronically ill) but we keep bouncing off one another. And to make things worse my boss gaslights me all the time at work. I hear my sister crying in the room now but I can’t help her, my mom is there. It makes me feel sick inside and I don’t know how to move forward w my life. Very very tired. Sad of making everyone else tired, too.
