13 yrs old and girlfriend... ?

Hey so I'm a 13 year old girl, and recently I got together with one of my friends for a sleepover, and she told me she liked me, I actually have/had feelings for this girl (let's call her daisy) and I said "omigod rly I like u too" <idek 
So we started just hanging out more, and she invited me round for a sleepover, aaaaand we kissed, but not just a quick peck, full on making out. Soo recently we had another sleepover and, hey we told some secrets, I told her I cut, she blanked me for a bit, then told me her secret, so apparently she kissed a 19 yr old, who then tried to take his shirt off etc...
Obviously I got a bit like, oh ok. Yeah cool. Play it off an that shit. But then later in the night she started saying how she hated her legs (let me just say this girl is the most beautiful person I've ever met) and I just suddenly got really sad, and just kinda went to sleep (I do that). So then after that she has not spoken to me once, and I just feel really alone, I need help but I can't tell anyone because nobody even knows I'm gay. So please can I have some help not hate. Please?
