I got in a big fight with my mom recently, I'm really lost and Idk what to do, My parents take my phone away all the time and they are mad at me most of the time. They don't trust me at all (they dont even let me do after school activities).I am going to be in high school next year and I plan on going to partys and enjoying my teenage years but if things keep going the way it is, I will probably be online schooled and it will suck, I need help from people who have maybe been through this and I just really want to know how to get my Parents to trust me and let me enjoy my life.

Gain their trust back.  As someone who struggled with gaining trust I know that you just have to listen to them and gain it back.  Its going to be hard but I am also going into highschool next year.  For now tell them about your day and school work.  try and keep good grades because that will help you to slowly gain it back.  But if you do keep doing this bad stuff you went EVER get it back so for now just listen.  Having fun in highschool and having trust is so much better than fighting with your parents and not being allowed to do stuff.   And its going to take and long time so dont think that it will happen overnight.
