what's a mother to do???????

being a mother is possibly the hardest job in the world. i have two teenage sons. one son is driving my to the edge of the universe. this is the child whom i have changed his dirty diapers, wipe his runny nose, sat with him through numerous hospital visits, got up in the middle of the night to help him through his bad dreams, while all the time loving him. now all we do is argue, he has become lazy, a poor student, and he has no respect for his parents or his once happy home. so the question is what is a mother to do???????????
