I (24F) am drifting away from my once close family and I don’t know how to handle it.

Tl;dr- My family dynamics are changing and I am growing apart from my family. I want to maintain some sort of relationship but don’t know how.

My family has always been really close and we have always enjoyed each others company. I’m talking about everyone in my household, not so much extended family. Now that I am an adult I feel like it is not going to be like this for much longer. I have chosen a very different life path than the rest of my family. I have a very demanding career and I am not planning on having any children whereas nearly everyone in my family is married and has children by 21. Also, now that I’m older I realize everything was not as perfect as I thought and some of them are very toxic people. For some reason it is still very painful letting go of the family part of my life. I never want to lose my mom but I am moving states away soon. On one hand I am relieved to have my own life without the toxic people but I miss my mom and sister so much and fear they will be mad that I left the family. It’s like everything I once valued and believed in is completely changing so fast and it is a bit shocking. I know it is part of this age in life but do any of you have any advice on how to handle maintaining a good relationship when life is taking you a different way? Also any wisdom on how to handle all of the changes that happen as you grow up would be greatly appreciated. I have never posted on here before so my apologies if this is a weird post!

Edit: I have never asked for advice on reddit before and you guys are amazing! Im not exaggerating when I say every post has made a difference. I knew other people had these problems too but reading all of your experiences has made this giant weight feel much lighter. I didn’t realize just how lonely this stuff makes you feel. You guys have made me and everyone here much less lonely by sharing your experiences and advice. Thank you all for showing so much support and care in your responses :).
