Our 15-year-old recently threw a fit, including punching, cursing and breaking things during the following incidents:
1) Took away make up after sneak purchase of $200 worth of make up without our knowledge.
2) Caught her using father's account to purchase clothes without our knowledge.
3) Turned off her computer when deliberately told her not to be on Discord while studying. (She has habit of just chatting without actually putting in work).
What do we do to stop these outbursts?
