I asked her to be my girlfriend today and she said yes then like an hour ago she said that going out feels like nothing changes is that bad or not? She is out the state four like a week so I won't shee her till she gets back

Wow, she gave it a whole hour, what a trooper.

This is her way of saying she changed her mind. You're in the friend zone, just enjoy her friendship.

I think she's just insecure maybe cause it doesn't seem like were back to the friend zone

Nope, if a girl (or boy) says "it feels like nothing is changed" then they are saying, 90% of the time, "you seem like you'll make a better friend than boyfriend" or "I'm not getting anything extra out of this, and I'm just wasting my time calling your my boyfriend".

When she gets back, try talking to her about it. If she is willing to work it out, make sure to set aside time for her to do special things, that you wouldn't do with just a friend, and you've never done with her before.
Don't try to make it too much, though.
