My mom needs help

My name is Ashley and my mom is Jana. My mom is the most selfless person I have ever known. She would give the clothes off her back. She has done everything right trying to get the post office to pay her her hard earned 26 year retirement pension. They have lied and promised her that she would get it and now she may not get it for months. She is too ashamed to ask for help, so I am doing it for her. She cannot pay her rent or bills on what little social security she gets. I work two jobs and have barely enough to pay my own bills and I can't convince her to move with me. Please anything helps! She is getting sick with worry.
