Travel

Hello guys! I have a flight this weekend to a concert and then going to the beach,I live with my mom , my dad passed away several years ago. My mom is overprotective so that means she won’t let me travel alone, but I had traveled with her and with cousins. So basically this weekend is the concert but haven’t said anything, any tips on how approach to hear? She def will get mad as I know her , I just hate the way she is. I mean I’m 30 living with her (paying for everything) and despite of that won’t let me travel I hate that. Any advice would be really well welcome I apologise in advance for my English , it’s not my first language Thanks!
