my mother is a regretful parent

she always said how she missed doing stuff like working, going out and being part of the world.

when I was born (I'm the eldest of two), she decided to become a stay at home mom to take care of me and raise me so she left her office job. since then, my father was the only one working to pay for the bills, etc.

I've heard for years how she feels like the world moved on without her. she used to travel, to go to church events, social stuff, and then she turned into a housewife and all of those things became just memories from the past.

I always hated to see her suffering with the decision she made almost 25 years ago. my father says it took a long time for them to finally have me, as my mom had some fertility issues and they were both 30+ yo. maybe this would make me feel wanted, but it makes me feel guilty, even though none of this was my choice.

I know she loves me and my sister, she does everything to us and for the house. but seeing her so sad breaks my heart in a million pieces. I really do wish I was never born so she'd never lose what she misses so much.
