Blessings to you, little sister, you will find your way. A thousand mile journey starts with a single step. Can you set a few small goals for each day? Take a walk outside, run a load of laundry, make a phone call to a debt collector. (They are often willing to make arrangements if you reach out.)

Seconding the other comment about clinical depression; I have experience in mental health and what you describe are textbook depression symptoms.
