Help for my daughter

Hello to you all!

My 17 year old daughter has been in treatment for depression since 2006. This past April, we left my husband and her brother to seek treatment for her in the US. She always worried about people suffering and was jealous of her brother. She had her period days before her 10th birthday, and since then has had acne. Usually on her cheeks and chin. She is fair skinned, and the acne is bright red with some pus. Usually she breaks out in lines and more before her period. She has taken many antidepressants without any change in her mood. When she is at her lowest she feels sad and cries herself to sleep. Last year she complained she felt tired and sleepy all the time. She took many naps during school and would fall asleep instead of doing homework. She is afraid of spiders. Like hot tea and graves ice cream. She has an aversion to olives, butter and mayonese. She hates herself after eating. She is afraid of gaining weight. She liked to feel hunger pains and controlled herself not to eat - she lost more than 20 lbs in 2months last year. Since April she started gaining the weight back. Her acne has aggravated since then. Now she has lesions around her collar and back, mostly on the side of the backbone, shoulders and arms. The lesions are bright red. Scratching her back, I can feel little hard bits coming out of the skin. Scratches always leave a red line on her skin. When she is nervous she bites and chews on her nails. She asks me to sleep next to her and hug her until she falls asleep; in the middle of the night she kicks and spreads herself all over the bed. She grinds her teeth loudly and talks on her sleep. Has vivid dreams which she likes to write down in a notebook. Her skin is oily and shinny in the afternoon. Since she was little she never liked anybody touch her nose. She is constantly blowing it - making a very loud noise (like a goose). Music has a calming affect on her. She feels better between 7-10am and worst 1-5pm. In June of 2005 she had an argument with my father and he stopped talking to all my family. She feels guilty she made him stop talking to me. She is sensitive to criticism, seeing others suffer and rudeness. She is a 10 on self criticism and 8 for others.
She has one BM a day, soft.
She loves to read. She asked to be home schooled at age 12 but she felt 'dumb and inferior' when she had to ask her father for help with work. She tends to dwell in the past. Needs to be loved. Likes surprises and small presents. Likes to be hugged when she is sad and to go to sleep. She likes compliments.
Never taken homeopathic remedies. She is taking an antibiotic for acne and, Zoloft and thyroid hormone for depression.
I appreciate any help and comments.
