After 9 years of living with my dad me and my sister moved today to live with my mom

Long story short my parents have been divorced for almost 10 years and we've been living with my dad ever since but lately me and my sister have been wanting to live with my mom and having doubts about it. None of them is married so it wasn't a problem but my dad had a fight with us yesterday and long story short it ended with him not talking to us for a day and i started having doubts about wheather or not we should move and i am kind of scared that it might affect my grades since it's obviously a big change and a big difference and the idea of change in general scares me in anything.

I know im not doing anything wrong but i don't know why it's so damn hard to adapt to change or adapt to anything and it is stressing me out for whatever reason and i dont know really.

But nevertheless we already moved but i just want someone who probably went through the same thing to tell me about their personal experience
