Nikita, it is not a problem with your parenting. If it were I would have 5 problem teens and not just one. Once a child reaches school age they are influenced by their own personal experiences as well as their peers. Please don't beat yourself up because your teen is acting out. You are but one single influence in there broader social network. Hang in there, be brave and trust that everything you do for your son is done because you are trying to do what is best for him. I openly admit that my life is in the crapper at the moment. My house is a mess, the washing is not done and I am struggling to cope but I also remain strong because I have to...... for my son.
