You are NOT in the friend zone anymore. The uncertainty might be annoying for you, but you are doing really great. She's just pissed off now asking herself "how could he do this to me and find another girl so quickly". She seems to enjoy creating drama, some girls need that. If you are looking for a stable and secure relationship, stop seeing her. If you are just after some fun and want her back, here's what you do:
Next time you see her, tell her you are just friends as she suggested, but as long as you are just friends you will continue seeing other girls. You have to be confident delivering this message to her. This will show her you are sought after and not willing to wait around for her. Trust me it's the best way to make her want you and be with you.
Take it easy and be like a rock compared to her mood swings.

You friend zoned yourself by saying "just friends"
I don't think that's the case. See how she reacted when you told her that you are just friends? That was the first time she said that you aren't.. I guess she's a bit of a drama queen but that's all good. Just stop worrying about your status and enjoy.
