Hopefully just overthinking

So I've been dating this guy for a few months now and I really like him, but he's been quite distant for the past week and hasn't really been acting like himself. Well today he messaged me saying he needs to speak to me and ever since then I've just been thinking the worst and I've been crying practically the whole day and I just can't stop. I just need him to talk to me as soon as possible, I need to know what's going on, so I can stop overthinking and thinking the worst. Even if what I'm thinking is true, I just need to know, not knowing is killing me and I just need it to stop.
