How do you guys deal with having to abandon single parent?

Hi there, I’m finally getting at that age where I’m thinking about moving probably abroad the issue is it’s just been me and my mum this whole time because my dad was a deadbeat and I feel horrible having to abandon my mum if I move because she’s not dating anyone either And it will just be her and our dog and there’s also no family that she can be with because they all live on the other side of the world so I was wondering if anyone has been in a similar situation with me what advice do you have?

Furthermore, my mum relied on me because my mum was an immigrant and even after all these years she still hasn’t really learned English all that much so she relies on me to translate stuff and set up appointments etc

Also my mum‘s best friend lives like an hour away
