I'm sorry hun, you have a lot on your plate. There is no ready easy answer to any of this. It sounds like everything falls on both your mothers and your shoulders. Trying to finance an entire household is very stressful and a hard thing to do. She's probably blowing off misplaced steam. Please don't take it personal. I really don't have an answer. Do you have a counselor to talk too? Somebody you can vent to to help relieve your stress? Life is tough, some more than others, so our prayers are with you. Please hang in there. Maybe she'll see that you are trying and have a moment of compassion? We hope.
