Hello,
Look this is really a crucial phase of her life. A misguided kid where she doesn't know what is right or wrong! Such kids are need of special care, love and support from their dear and near ones especially parents.
Yelling at her / just blast for one or other things is Not the answer at all. Proper
counselling n support will surely help her out. I would suggest you do as follows :
Start spending more time with her as her friend. Share views on one or other things /topics. Go slowly. Gain her confidence so that she speaks out about her feelings n thoughts.
2. Involve her in some sports activities & also in some hobbies. Instrumental play. Music and all.
3. Good books, spiritual videos - discussions will also help. Overall to say just let her be busy with some constructive directions.
Internet should be stopped gradually. I hope after all this you can talk to her giving someone else example n tell stories n see her reactions.
Once she starts understanding the difference b/w good n bad. There won't be any problem left. A trained counsellor will be a better option.
Hope I have answered your query. Let me know if I can assist you further.
Take care
