I am sorry what your sister said to you, That was totally uncalled for and rude. If any one should get the mothers day award. It should be you

You were taking care of her children while her and her husband were getting drunk and arguing all the time, I would have went off on her and reminded her of that little detail she seemed to convienly forget, And you have every right to vent and be angry about your brother and expecting you to take care of your sister in her time of need, And then your problems at work, I would have exploded on all of the things you mentioned, Your a stronger woman then me, Any way I am glad you vented you have to get your anger out some where, I think you should start worrying more about yourself and ignore other people's negativity
