Sign: My Child Just Doesn't Seem Right
"One day I was looking at my daughter and thought - who is this person? Her behavior has become strange and unpredictable. She acts as if her family doesn't exist. I can list all the things - but really in the end it's just that she doesn't seem right. She isn't the same person anymore."
Taken together with other signs - you get this one larger picture: a teen who just doesn't seem right. Trust your instincts. While it might not be drugs that are influencing these changes, you should not ignore them or assume they will simply "go away" in time. The worst thing a parent can do is ignore their strong sense that something is wrong and let the teen act however they please. Talk to the teen's teachers and others who know him or her. If you get a general consensus that something is off, take action and seek professional advice.
