I know some who moved out very young, under eighteen because of various reasons. One being that they did not get along with their parent. I know some who choose to live with their parent or parents, to save money or because they have no money. They are in their mid twenties but they don't believe that it's terrible to still live with their parents after high school.
I live in NY so the rent is considerably expensive. I partially understand why someone would want to live with their family to save money on rent. I have wanted to move out since I was in high school and I never planned to return back to my home town. I do not get along with my mom at all and I am not close with my dad.
I recognize the practical aspect of living with my parents for a few more months, maybe even a year. I cannot tolerate a year, but I could a few months if there is a good reason for me to. I have lived with them for a year and a half after I left college abruptly my sophomore year.
I just can't figure out if my reason is good enough to stay or to leave. My issues with my mother has been going on for years and there is nothing I can do to immediately or even slowly fix it. I have given up, pretty much. I love her and I can tolerate her in small doses. But that's it. Living with her is a nightmare. Her presence in my life is disabling, sometimes straight up emotionally abusive. I am not a wimp and I am tough so I won't crumble, but I feel that it's not something that I should have to deal with any longer, in any extend.
I am old enough to move out, even if money will be very tight, even if it's "impractical". I have spoke to some of my friends about this, one of them thinks it is extremely impractical and I should just save money right now to move out later or even not at all until I have finished college. The other one is very encouraging.
