On the off chance this isn't a troll, you should take some time and investigate objectivly what she's saying. A lot of people here have a great deal of personal expereince. They're about as close as experts as you can find in this paticular field, and it would not be very learned to disregard everything that's said here.
Look, it sounds like things are very tense at the moment between you and your daughter. In the end it doesn't really matter what's said online because you don't have to deal with us on a daily basis. The same cannot be said for your child. What IS important to remember is that you need to take her feelings into consideration. She may honestly feel that she was neglected; even on some cursory level.
TALK to your kid, try to be understading and patient. Even if you don't agree with her, listening and making her feel heard can go a long way toward a healthier and more close relationship. And try to keep an open mind, it's quite possible that things happened that you didn't know about. Chances are they did if you were out of contact for a prolonged period of time.
