issues with my 15 yr old daughter i think depression need help.

Hi there i am new to this site, i have a almost 15 year old daughter who i believe is suffering from depression , some symptoms include, lose of appetite , wanting to sit in her bedroom alone 247 away from the rest of the household, angry outbursts, other times looking pale, flat, and just in tears and saying she feels down , needing to be told to self care, shower etc, i have taken her too a local mental health centre where she has been seeing a lady for the last 8 months, too me it is not helping my child thinks the same its just pretty much talking about her feelings, well it helps for 5 minutes then wen we are back home its the same cycle, she has also seen a phycistrist at this centre only once though and he seems to think she has some type of seperation anxiety being away from her father and i ( she is always with us and has Never been babysat over night by in her 15 yrs of life by family or friends. i have pulled her out of high school since april last year as she was being bullied and the school kept letting it go and i was sick of seeing her upset crying and not wanting to go to school i was goin up the school like a raging bull trying to get it to be stopped so my only option was to pull her out of a unhealthy environment and push for home schooling via dubbo distant education it took a few months but i got her accepted she has been doing the school work here and there not as muvh as she should be due to being overwhlemed, i must add my daughter suffers from a moderate intellectual disability and she has trouble managing or exspressing her emotions it makes it hard i hate seeing my daughter sad and not being able to help i have asked for medication or something like a mood stabliser but all you get from the doctors around here its a attention seeking thing or her angry outbursts are her being a rebelious teenager witch is a crook of bs my child is the nicest caring kid there is and shes not feeling like this for no reason , she dosnt have alot of friends, i try and get her out of the house to do activities but she gets over them and wants to go back to her room so i just agree , my daughter is in a stable environment her father and i have been together 16 yrs, she is the only child, we do not drink, iphyscically fight or use illicit drugs, she gets the best of everything and never goes without i dont understand where all these feelings are coming from but it breaks my heart as a mother to see her down and crying, she has also come too the point where she was trying to self harm ( yes this has been shared with the local mental health team at the center where i take her, wasnt too concerned about it again it was apprently the form of attention seeking, it was only scratches, no loss of blood etc but still not the bloody point, she also got passed along too another organisation witch give her some kind of support worker that takes her out once a week for an hour , thats if she dosnt cancel but an hour a day is not good enough i dont think this support worker dosnt even touch base and check on her throughout the week so im seriously thinking about canning that .. i took her to the doctor yesterday and expressed my converns again for the 10th time and told them i know my daughter it isnt attention seeking shes actually feeling these emotions its not forced or faked, the doctor agreed to do a full mental health assesemment next week and for her to skye with another doctor to work out a plan and cause of ation for her heres to hoping, just looking for other people going through somothing similair as its hard feeling alone and having no one to talk too . the doctors told me when im feeling a certain way drink a glass f water or go for a walka round the block what a crock of bs...
