Forceing me to go to Family functions?

im 22 years old. i still live with my parents. unfortunately, i been going crazy and wanting to move out with my boyfriend! but the money🙄🙄 anyways i never been a people person nor like to be around family and people... I just get bored and annoyed.. especially my family... So my mom forces me sometimes to go to Family holidays or birthdays and i wanna stab her cuz she shouldnt be to force me to go anywhere if i dont want to. when i move out , i will not be going for christmas with my family or nothing because i like to be excluded from everybody and hate ... So i told my mom she cant be forcing me to go anywhere i dont want to go , im 22 years old, if i dont want to hangout with them on Thanksgiving i dont have too!! 😒im just like that. So how do i avoid that??? When i move out , should i block all familys numbers so they wont contact me with anything? Sounds so harsh and mean but i have been bullied in my family and treated badly... everyone talks shit about me but i never do anything to them. Im going to college and have a fulltime job. i hate family! Blood isnt thicker than water!!
