Hi lil dani07,
It sounds as if your mother has depression. You may need to have a family intervention to get her to see a Psychiatrist for medications.
You may need to gather a few family members that see what you see and sit her down and have them tell their stories of how sad she is and how she would benefit from help.
Have a psychiatrist appointment lined up, tell her about it then and insist she go get, at the very least, an evaluation.
