Construction, work, kids etc..etc... are lame excuses. I asked you a question earlier? I ask the same again here! Would you continue to give similar excuses if one of your immediate family member (you, your H, your kids) are sick and need 24/7 home care? What would you do? Looks like you have a history of misunderstanding and sibling revelry in the family. Your older thread says that you do not share a great bonding with your mom, and having her around can either depress you or affect your marriage. It also appears that you have another sibling/sister who is having a better relationship with parents. Having said that, it takes two to tango. I can't judge anyone here. I don't know what is behind your problems with your parents and siblings? It seems your brother & sister are maintaining good relationship with your parents while you have all the problems with both sets. But these are irrelevant when it comes to caring for our parents. You have a role to play and a responsibility to share. If you can't host mom, offer something you can. You can either accompany her for the hospital trips, stay at hospitals, chemo schedules, etc.... You may chose to take a long break from work and spend with your mom at your brother's place. You may cover her medical expenses, transport costs etc...If you do not have money, take loans. If construction work is the problem, stop them for a while and take care of your mom when she is in need. But don't do anything out of compulsion. You know better about your circumstances, and the history between you and your mother. If she was impartial towards you, and caused a lot of heartache to you and your family in the past, then she can't expect you to be a saint. Do whatever it is possible, and whatever it is naturally coming out of you. Love has to come naturally, it can't be forced.
