Sorry about your situation, I can't imaging coping for a whole week with someone elses kids. I think you are being too nice. You need to refuse to take care of them. Have them put the kids back in the car and leave. You are not a bad person for doing this. You need to look out for your mental health. Your siblings are taking advantage of you. You attempted suicide for a reason. If you are constantly around those triggers your not going to do well.Sit down with your mother and talk with your siblings about what you told us on this site. Tell them to line up alternative child care. I hope this helps
