[21/m]Girl gets sick(too drunk)[21/f], i take care of her now things seem different/awkward/not the same

Quick back ground. Went out with her 2 times alone and have been hanging out with her and friends together for about 1 week. We texted a lot everyday and she initiated the "talking" by asking me out.

We go out with friends and have drinks. We then go back to our friends house. I can tell she is really drunk, but not sure if she passed the threshold of puking her guts out. She is sitting on the couch(everyone is just hanging out in the living room) and says she needs to go outside and tells no one to follow her. I respect that and wait 5 minutes then go out to check on her. She is wandering around and is clearly too intoxicated to be outside alone. Basically i tell her we should go back to her apartment and she eventually says okay. (She was very very drunk and needed to go home. The people at the house we were at were leaving/ going to bed). We get home she goes in the bathroom gets sick, i go in and help her up and helped her to bed. I tell her I'm going to go, but she said she doesn't want to be alone. So i stay and about 5 minutes later she runs to the bathroom. I hear her throwing up. At this point I'm not going to leave her in her bathroom throwing up. So i just sit in her room for an hour. Then i get her up and she is feeling better. She makes some food and then we lay on her bed and talk about the night(because she didn't remember a lot). I then leave around 6 am go home and go to bed. We really haven't talked that much (2 days have gone by). Some of her text seem short and we don't text throughout the day. So, i don't know did i do something wrong? Is she just really embarrassed, and avoiding me? Am i just being stupid and nothing is wrong?
