So, today I spoke with my counselor and we were talking about me trying to make sure my siblings are taken care of and doing anything I can to keep them safe.
She said something that really made me think. "But do you really believe it's your responsibility to do that"? It shocked me, because of course I thought it was. It never crossed my mind that it wasn't. But, I thought about it for a minute and had a realization that I'm putting too much on myself. I can try to help them, but it's not my place to feel guilty or let myself get so upset because I'm not able to help them. That's ultimately my mom's responsibility.
Even now I feel selfish thinking that way, but it gets a heavy weight off my shoulders to have a different perspective on it. It's not my fault that they are in the situation, I have done all I can and will continue to do so. But I can't hold myself accountable for what my mom has chosen/will choose to put them in.
I'm starting to finally get a better mindset, and it's a huge step in the right direction to overcome my depression. For anyone struggling with a similar situation, it's not your responsibility. Take a step back, stop pushing yourself to do what someone else should be doing.
