Hi, you’re getting a lot of bad advice., normal doesn’t equal good or healthy as the “new normal” is skewed to the pathological with so much depression, addiction, mental health issues etc. You are totally right to be worried.
At 18 she should be working a job and learning the value of the money she is wasting. She should save and pay for her education so she values it. Besides that she will learn character lessons
What is being taught in uni is nonsense to the point where a regular college degree is not preparing anyone for a successful career, it is almost useless, and yes, unfortunately it is”normal” for people to have an extended, pathological adolescence frying her brain with booze, etc.
In my experience the people who are the most successful are the ones whose parents tell them to work and pay rent. At least for a year. Uni is toxic but it’s a big industry that parents l/kids are bamboozled into supporting with some false idea that it is necessary to have a good job, life, etc.
if she isn’t an academic on track to becoming a licensed professional where the degree is essential (medical doctor etc) I would make her work and learn some humility. It really is not in her best interest to let her keep in this path.
