After some recent shit with my family I've finally made the difficult decision that I need to cut them off one day and that I'm not going to have a relationship with them going forwards. When I get the chance to change my legal name I'm also going to change my last name too as a way of separation from them all. I've already picked a new first and middle name but I really have no idea what to do for the last one. Like last names have histories behind them and a lot of time it has to do with what country or culture you've come from so it would be weird of me to pick a last name based in a culture that I'm not from.

Has anyone else gone through this? Do you all have any advice for how to start choosing one?
