I need help with deciding what to Do?

You're in a wonderful spot in your life, because you are 18+ and have these decisions available to you. What's unfortunate for younger individuals is that they often can't escape their situation because they aren't old enough to make those decisions without their family members.

That being said, I would do what is best for you. Your mother and father do not have to live inside your head. They do not have to live your life. You do. So, if you are unhappy, do what will make you happy -- or what will give you the best possibility of happiness. To me, that seems like going to live with your aunt, especially if you get along and your aunt promotes a healthier living environment than your parents.

Do what is the best thing for you, to secure your own wellbeing and possibility of happiness. You should be your first priority, and getting away from the situation may be the best thing to do due to the circumstances. Since you're in college you don't have to worry about custody and all that, so in theory at least it isn't as difficult as i could have been had it happened a few years ago.Take some time and think about it, get your priorities straight. And also, I think it would be a good idea to report what your father said to you, threatening lives is never something to be taken easily. As for your mother, she is an adult who has a right to make her own choices, wether you like it or not, and also deal with the consequences. Perhaps you could try and convince her to go to a clinic and get help with her addiction.But you are your first priority. Do whatever feels right, what makes you happy and what you can live with. Think about the future you're setting for yourself, and what you are willing to do to get there, and wether or not certain people will be included in it.

Thank you so much for your advice!
