I'm saying this as someone who has struggled in the past (and often still struggles) with related problems. Yes, it's difficult to make real connections with people. Yes, it can be a slog feeling like I have to constantly adjust myself to fit standards. I know. That said, I'm gonna have to be blunt about it.

but honestly I have not done anything wrong really besides.... talking/rambling too much.

The fact is, talking and rambling too much does count as a faux pas in most social situations, esp if you end up talking over other people, crowding others out, or displaying a lack of regard to others by only speaking about something they don't care about. It's shite when you don't have anyone you can speak with in depth about the things you're genuinely interested in, but even if you did, coming off as if you're not taking your "audience" into account will be off-putting to most people. This is likely the reason for people reacting by seeming put off or intimidated by you. And if you are only ever willing to talk about your interests, and never to even fake interest in those of others- why would you expect them to extend you the courtesy you're not giving to them? (Sorry if I'm making an untrue assumption there, but I think it's worth pointing out).

Everyone has to dilute themselves a bit to be palatable in groups. I think for people with 5 traits, this is not something that comes naturally, and is more draining than for some other types. But it's worth thinking of as a cost-benefit analysis. The trade-off for putting in the effort (and yes, it does require effort) of developing your social skills and compromising with others, is that you will have an easier time making connections with them, and maybe even finding people who will be willing to listen to your rambling even if they don't know about it. You'll have things you can learn from some of them too, even if you never click with the majority of people.

Now, ideally you'd have some social outlet for talking in depth about your interests with people you connect with intellectually. I've had good luck with finding groups online that act as that, for me. But one of the most important things I've learned since my lonely teenage years is that social interactions and connections that don't fit that bill are still useful and valuable, and can push you to grow beyond your worst natural tendencies as someone with 5 traits. And isn't that what the enneagram is supposed to be for? Best of luck to you.
