we now get to realize that these so called siblings are even doing better than my mum

Ah reminds me of my life lessons. My mom used to do that for her siblings and after her death, her siblings don't even care for her anymore, they don't even remember her...I also prioritize myself because I have seen people enough. I also believe that after fulfilling my needs, I can help others also...

Thanks for sharing such a valuable perspective...

Goodluck...
