Going through the issue you spoke about, I could sense the worry in you. As a parent it must be quite traumatic to see your child in this situation. You have approached this platform to seek help, maybe with the good intention of helping her out and also help yourself as you sound anxious and helpless to deal with this situation back home.
You mentioned about few problem behaviours that you have observed in your daughter. Let me explain these behaviours from my knowledge. What we observe as problem behaviours are usually a result of inner struggle that person is going through, that is not visible to anyone interacting with him or her. What gets observed is, aggression, social isolation, laziness, blaming, easily threatened, depression, argumentative and many more. Now, some of other root causes could be unmet emotional needs and low self-esteem.
It is usually a cry for help as it is quite painful for that person to be in this state, creating immense anxiety which again is dealt using unhealthy ways, for example one of the ways in your daughter’s case is finding solace in phone.
Another aspect that I would like to bring about, which also may not be easy to digest is most problems are co-created. Which means, both the sides have contributed towards starting and maintaining the problem. Parents are a big role model for children, they mirror their actions and ways of dealing with situations, both positive and negative. Well, just like Murphy law, impressions of stressful situations handling last longer. Then again, has there been a permission to express feelings and needs without undue judgement in the family.
Having said that, I do empathise with you, being a parent myself. Parenting can be very challenging and we are not born with parenting skills. My intention here is to show the mirror, as at times we can be mirroring the parenting style received from our own parents. There can be many different ways to explain the problem but spending too much time in this zone is not helpful.
What may be helpful is to start from where you are with the problem now, as past cannot be undone. Hope and help is there, provided both sides are open and ready to receive help. Some useful thoughts have been shared by someone in the earlier reply to this message. Thank you for bringing up thoughts from your personal experience.
That is it from my side, hoping it throws some light!
