Friends - what do I do

Hayley • hi! I'm Hayley 😊
So my mom, me and my sister took in a girl(she'll be 18 in April) who was my neighbor about 3-4 years ago. She was a 14 year old who moved in with her aunt cause she and her mom fought 24/7. Her whole family smokes pot and everything. Her aunt does cocaine and other major drugs. Then one day her aunt kicked her out and she had no where to go so we took her in. I'd already known her for about 3 years before that. So now she's pretty much my sister. We fight, laugh, share and do pretty much everything together. We both had the same best friend named Amanda and we all did everything together. Then Ciera started getting annoyed with the way Amanda would do things and she would just be sassy and irritating towards Amanda because Amanda got a boyfriend and started hanging out with him more. Then Amanda totally ditched us and does tons of drugs now and that was about a year ago. I've moved on and my best friend now is a girl named Kaitlyn and we've been friends for about 5 years. I've been spending so much time with her and I love being with her. But lately Ciera has been wanting to spend time with us and everything and sometimes I don't mind but I feel like she always wants to go out and do things with me and my friends all the time. At first it didn't bother me then it started to so I talked to her about it and told her it bothered me. She got all sensitive and mad and said "well I don't have any friends, etc." I said okay that's fine and I let it go. Well when I'd hang out with my friend Jess, Ciera would say "Can I hang out with you and Jess?" and I'm like "um.." and now she hangs out with me and Kaitlyn a lot and sometimes it doesn't bother me but when I just want it to be me and Kaitlyn and she wants to come and it bothers me! I don't want to talk to her about it cause she gets all mad but I don't want to talk to Kaitlyn cause I'll feel like she'll be mad at me for being selfish of her cause she can be friends with who she wants. I just don't want us all to be best friends because I don't want the same thing that happened with Amanda to happen with us and Kaitlyn. I don't want her to get bored or irritated and bitchy towards Kaitlyn because she's my best friend and I don't want to not be able to bring her to the house cause Ciera doesn't like her!! it just makes me angry because I want my own friends! I hate having to feel obligated to bring her with me because I feel bad. I hate her asking me all the time. I understand it's hard for some people to make friends but I just need her to try. Because I'm not always going to be there when she needs friends. I don't know what to do and it makes me so upset 😩
