Pray for my sister to have self-control

Pray for my sister to have self-control, She is always grumpy, I don’t know what happens to her, she is not like that before. It started when she meet her friend at her school. She loses her self-control and she always demanded everything want she wants from our parents. My parents felt depressed about her attitude. She change a lot, we always push her to go to church but she didn’t want to go instead she wants to spend her time with her friend. I don’t want to judge her friend they are a bad influence on my sister.

Pray for her that the Lord will help her to make a better person also guide her and give her the light to the right path in her life. I miss my little sister who is kind and joyful.
Thank you so much!
