Do you feel you’re obligated to take care of your siblings once you make it? I’m not doing it. I don’t care what they going through. That’s why my mom

Do you mean financially? I would financially help 2 of my siblings. The same two I give emotional support to. The other 3 I would help if they were hurt/hungry, but not give too much of myself.
It’s less about them not being deserving, and more about protecting myself.

I never made it and I take care of my mom lol but besides that I have already and will always take care of my family. I just have personal values that I can't deviate from but I don't blame anyone for not wanting to do that!

Never obligated, but I would to some degree. I thought about it yesterday actually, and I think it can cause issues if you help them too much. They'll start to expect it, become dependent on your help, and not really get any happier at all. It's better to just be of support when truly needed.

My older sister takes care of me financially,I absolutely loooooove it. She spoils me sooooo much. Back when we were younger before she started working she would promise me that once she made it she was going to spoil me. She was very very very faithful to that promise. I didn't ask her to make it,my parent didn't make her,she just does it herself because she loves me. There is no obligation.

You have it wrong, she is in first position, you are second. She doesn't have you on her paperwork because that is her choice, and you have inherited it, so now you also do not care.
It's like when a kid is abused by their parents, when they have kids they will abuse them, it's an inherited learning thing.

Obligated? No. Willing? Yes
