What happened?

What's happened to you? You can share with me , I may relate you

my sibling who is younger kept back answering me infront of my parents, and she's 20. They didn't do anything about it, instead asked me to be quiet

and trust me, I didn't provoke her or anything, she's just been angry with me for no reason. I've been nice to her.

I just can't stop thinking why, she's always been a paranoid

if it were someone else, I'd just stop talking, but it's my sibling, and trust me, I was the one to initiate a conversation, or anything like taking her out, buying her clothes dining outside. I was the one to set things right between both of us everytime,. it's never been my fault. and she's never apologitic... it just makes me wonder why am I doing this for her. Just because she's my sibling. there are far better people on earth, who are not family

May be she's going through something or any personal issues just give her some time , you are doing your part as elder brother correctly , just wiat

I am sorry, you have to go through this, you are such a nice person and sibling. it's not your fault. Appreciate yourself enough because you are being kind here. There are always going to be people pulling you down.
