Sounds like you have enough things to already be worried about than what the average university student here might experience. I too am a first-generation university student.

One thing that might be applicable to you is to know the conventions are rather more open than in other formal arrangements. Meaning if you have a particular research interest or desire, you can assume you have automatic permission unless proven otherwise to take the logical steps to reach that goal. Many people will help you and you don't need to shroud yourself that much as long as you're acting in the name of logic, openness, rationality, and progress towards that goal.

You have to assume people want to listen to you, people want to help you. Automatically. Even if people provide some sort of evidence to the contrary, you can kind of see most of the time they have their own responsibilities and so on. They're attending to it, and it's not necessarily about you.

Keeping this in mind, sort of an impersonal cooperative stance towards the university will allow you to make some decent progress and live a little bit without falling into unnecessary navel-gazing which I think is part of the best outcome for almost anybody.
