Emotionally drained

My parents got a divorce I don’t talk to my mom but I did attempt to and I couldn’t do it so I had stopped texting her and all my friends are going to an amusement park and I can’t go cause my mother is going. What do I do to stop thinking about her? Get a restraining order? I have no clue what to do about this and my dad doesn’t understand anything that’s happening and becoming the woman of the house so fast he expects me to keep the house clean while my brother plays Xbox
