<human>: Give me a shortened version of the text

I (m18) have been talking to a friend (f16) for about 2 years,.
We talk pretty much every single day, though we never really meet in person.
About 4 months ago they were messaging me about 1am from what I think was a party, I was tired and had work in 5 hours but stayed up to talk to her. She seemed to be acting different from usual, she was being really nice and super upbeat (she's usually a ton more reserved), I replied to her messages asking if everything was alright, what they were up to and the usual things, but their behaviour seemed so different from what it normally was it freaked me a bit, so I sent a text saying that they were scaring me a bit.
~~Point~~ I think that may have caused a problem.

We still talk every night and most day, but she just seems to ignore me, the conversations aren't the same and things have become quite strained. It feel like an idiot for being worried about this even though we still talk all the time.

I almost always say the wrong thing when the opportunity arises but it never has seemed to bother them before, because they know I don't mean to be rude.

I really value their friendship and i'm worried that this is going to turn out badly, what I messaged is constantly in my mind, please help, what should I do?

If any extra details are needed please message me or something and i'll provide them a.s.a.p

Thanks Reddit :)
<bot>: I think i said something stupid to a good friend which has caused them to lose interest in talking with me. I don't know what to do.
