I didn't mean to make this so long, but I feel for you and have found the best, most logical and sensible author on the subject...
I am a follower of John Rosemond, the best parenting expert and author you could find. He describes your daughter's behavior to a T in his books, and teaches how to change your parenting in order to get her under control. His book John Rosemond's Six Point Plan for Raising Happy Healthy Children would be an excellent place to start. She obviously doesn't respect you; it's time to lower the boom and get her under control, as she is only going to get worse. When she is having a tirade, put her in her room for an hour, and then if she is calm (and in my home the room better also be clean) she may come out. We turn the doorknob around on the door so that we can lock the door and our kids can't come out when they want to be obnoxious. It gets her out of your face so that it is not so upsetting to you and the family and you can also calm down. Also, take away what is most dear to her (a favorite toy/blanket/privilege/whatever) when she is being terrible, and give her a week or month to earn it back with good behavior. Also, tell her what you will do rather than telling her what to do as often as you can think of it: "I will open the door in one hour if there is no screaming and the room is clean"; "I will return the beloved toy when there is no sassing for a week".
These ideas are just a start. His website is www.rosemond.com, and his newspaper column last week was excellent, and will be continued this week. The way most people parent these days is a far cry from the child rearing of our grandparents, and they sure didn't have all the issues we have today with violent, spoiled, lazy, bratty, self-centered kids.
A couple of the first things that John Rosemond always says are that the marriage is the primary relationship in the home - the children come after that; and, you shouldn't be paying so much attention to the child that she has no need to pay any attention to you. She should be keeping track of you and what you are doing. Don't anticipate her "needs" and take care of them. She needs to come to you for her needs, and be concerned all the time with where you are... not the other way around. I know this is totally backward from what so many parents do these days, but if you watch their kids, they are helpless, insecure, and often disrespectful to their parents. Also, tell her "no" as often as you want, and stick to it. If kids don't learn to deal with frustration, you end up with adults that can't handle frustration - they are the ones throwing things, going postal, not getting along at work, etc. The more "no's", the better, and stick with it.
Anyway, I can't recommend John Rosemond enough, and you won't hear what he has to say from anyone else, and his methods worked on his own kids, and they are working on mine. Another thought that he says: say what you mean, and mean what you say. Don't just hope that she will do what she was told (like stop climbing on the guests). Tell her before hand that there will be none of that, and as soon as she does it, march her off to her room for an hour. That will get the message across to her, and show her that you are serious. Be so vigilant with everything she does, and she will start behaving. It will take a few weeks, and she will test you all day long, but this boorish behavior needs to stop.
Also (I keep thinking of things I've read by John Rosemond), the more attention a child gets, the more she wants, and will whine/screech/howl and behave poorly to get it. It's not that they need so much attention. Just as the more candy a child gets the more she wants, the same goes for attention and anything else. They don't need to be tended to all day at her age; that is just modern psychobabble and breeds the kind of behavior you don't want. In order to become an imaginative, creative, independent child/adolescent/adult, she needs to learn to play on her own and entertain herself, knowing that you are always there if she NEEDS you. If she can't entertain herself, she is lacking in imagination and creativity, and is probably watching too much tv and probably has too many toys. My boys can entertain themselves for hours, with just about anything (a rope, foam paintbrushes, legos, etc. have been popular lately).
Good luck to you, and I hope you get help with whatever is dragging you down and making you tired. I've been there myself, and started seeing a Naturopathic Physician, who finally diagnosed me with Hashimoto's Thyroiditis. No MD ever figured that out; they would just do the T3, T4 and TSH tests, which were always normal, but never bothered to check for thyroid antibodies, which mine were very high, meaning that my body is waging an autoimmune attack on my thyroid. The ND put me on an anti-inflammatory diet and has me taking iodine and other things, and I'm like a new person, without drugs, and I have finally gotten pregnant as well, because of her, and the bald spots on my head have started filling in after five years of a receding hair line. And all this without drugs. It was a little spendy, as my insurance didn't cover her, but I've gotten more help in 8 months with her than in 15 years of seeing MDs, and with all the deductibles and copays, I probably didn't spend any more with her than I would have (getting no help) with my insurance at an MD.
