My 15 year old is acting strange to me, she looks distracted most of the time she's not in our world she gets depressed alot and won't talk. her emotions/feelings are just flat she gets voilent angry for no reason, she smells odd things she finds it hard to explain things and she finds it hard to understand simpole things. She's constantly looking around as so if things were there she laughs for no reason, I do know she's paranoid she always thinks people are taking her thoughts also inserting thoughts into her. She acts in a strange way. She makes no sence when she's talking, she looses focus of reality. She tells me she has bizarre dreams. When she gets in a arguement she'll go exream with knives and other sharps. She finds it difficult to do simple tasks. She has weird movements of her tounge, her arms jerk and twitch she feels random touches on her body. Is my daughter depressed or anything?
