Self esteem almost ruined my vacation.

[Idk_anymore]

So I went on vacation to Cali with my dad and stepmom as well as her friend and her daughters which are my age, one of her daughters which we will call Iliana brought along her two friends, which me and my brother ended up spending all vacation with, I’ve never met them before this vacation there just kinda outgoing and started trying to get to know us, and at first i assumed they just liked my brother because almost every girl does even my ex but the more and more I spent time with them the more i liked illiana, the whole trip I kept checking in the mirror to see if I looked good because I’m so damn self conscious of myself, I’m not ugly but I’m not amazing either, anyways there was one day where I looked in the mirror and came to the conclusion I didn’t look good enough to talk to her which I do a lot because i had acne, I’m taking medicine for it now so it not nearly as bad and I get one here and there every once in a while but I’m still really nervous somebody will spot one and think I’m disgusting anyways I ended up having an anxiety attack in the bathroom...luckily no one saw but i got really depressed and slept the rest of the day, the next morning I looked fine and tried talking to her and i spent all day with her and actually enjoying myself for the first time in a long time, later in the day she called me in her room, and her and her friends decided they wanted to take a nap and told me and my brother that there was a room downstairs that had two beds, I assumed that me and my brother would share a bed and her and her friends would share the other one but I ended up sleeping in the same bed as illiana she laid down facing my direction and I tried moving closer but then...her mom Walked In lmao she told everyone to get out of the room and that where cleaning the house in the morning. She fell asleep up stairs and her dad told her older sister to go on a beer run and asked us if we wanted to go with her I said I would because it was really late and I didn’t want her to go by herself, we started having a conversation when we got in the car and it turns out she is really cool, eventually she started asking how old i was and some other things which made me think she might like me, she was really cute but i kinda didn’t wanna fuck up whatever was happening with illiana, so we got back and illiana was awake again and she decided to go fishing we started talking and she told me that i was awkward, too nice and a bunch of random shit which gave me the impression she didn’t like me not to mention she kept asking my brother questions, knowing that he liked one of her friends that he was spending most of his time with. but then she turned around and asked me to lay at the end of the bed and talk with her later that same night, it’s weird and confusing to me. I just don’t know if she likes me and I already have a fucked up self esteem I just really like her and don’t wanna get hurt. I had an amazing time with them especially her but I kept bringing myself down and second guessing everything that happened with her, I keep telling myself what I would do differently. Does she like me, how do I fix my self esteem idk?
