Why did I get denied from for ssd benefits because I work 22 hours a week? l call in sick so much that I don't even think I average 22 hours a week.

I am barely functioning. I have childhood trauma which gave me PTSD. Then my 20 year son died several years ago. I attempted suicide and the doctors informed my husband that some damage was done to my heart and my mind will probably never be the same. It is progressing. I have no will to live. I am confused. I don't understand things anymore. If I got on disability, I would quit my job in a hot second! It's too overwhelming for me to go to work. I tried calling the number provided a second time to appeal but the chat person Melissa cut off our chatting probably because she saw that I called before that. I have lived like this for over 40 years. Why won't NOLO help me?? Or anybody??
