@Rachel_Blackruin, honestly, I haven't been around you long enough to know whether or not you're hyper for sure. But if your friends really went through and said that out loud, then you must have done it at least once or twice in which they feel like you aren't going to change. I, personally, don't really think you're overly immature or hyper, and of course, I can't really judge you on your maturity as I don't know your age either.
So my advice is to talk to them about it. Tell them that what they said didn't stand out as the nicest things to say to you. Then, (make sure you do this), ask them to give you real instances when you acted like this. If they give you a list, then make it up to them. Make a conscious effort to do better around them, and I'm sure that they'll forget soon.
However, if they can't provide a list or even good reasons, and they still refuse to at least try to work something out with you, then I'd advise you not to hang out with them for a bit. Reach out to them if you can, but if they really want to end things then there's no point in trying to make them more annoyed.
Overall, pray for them and the situation. You as well if it turns out that you are hyper or immature at times. Anyways, that's just what I think.
