controlling parents

I'm so annoyed and I need to vent. I am 19, almost 20 and my mom still treats me like I'm 15... I want to be able to go out and party and do shit and she always says no! My friends are throwing a party at a hotel for Halloween and my boyfriend and I were gonna go and get a room next to theirs so that way when we were ready to crash, we could just go next door cause I'm not trying to sleep around these other people (known them for years and they're ratchet) anyways my mom said no and that I go out too much.....🤔🤔🤔 I go to work everyday basically and that's it. I hang out with my boyfriend when we're BOTH not working but other than that I don't do much. I feel like this is the time for me to start living life and I feel so held back... anyone else ever feel like this ?
