Welcome Never. I echo Zoo, you are not a failure. Everyone can look back with hindsight and wish they had done certain things differently. It doesn't help to dwell, you will torture yourself.
DS1 attended a CAMHS unit as a day patient for a while, he made a lot of progress there. I wish he could have stayed, as it was he stated longer than normal because there wasn't anywhere for him to move on to. He now has an EOTAS package and progress is slow.
Would DD be able to engage in less direct therapies? Does DD have an EHCP? If DD can't manage F2F or live online tutoring could she access recorded online lessons she can dip in and out of? As part of the children's services involvement did the disabled children's team assess DD? And a carer's assessment for you?
Muddling glad the TAF went well.
Fferny education can always come later, MH has to be the priority. It may be DS can cope with a reduced number of GCSEs. You should push for medical needs tuition and apply for an EHCNA.
Damn are the college making adjustments? You can apply for an EHCNA for further support. Does DS receive PIP?
Crudite one of the problems with CAMHS is you have to keep chasing them. Legally, under the Equality Act, DD has a disability, but it doesn't really matter whether DD accepts this or not.
You can apply for an EHCNA yourself, IPSEA have a model letter you can use here. Can DD go in a quieter entrance, a bit earlier or later so it's quieter? Could a key worker meet her every day. School could do more to make school easier for DD so hopefully getting DD to school is easier. Depending on her needs that could be: a time out card, a quiet room when needed/at break/lunch, moving 5 mins early, laptop, notes, placement within the classroom... Do the school offer counselling or interventions such as drawing and talking or emotional literacy support?
It has been a long day, I'm sure it should be bedtime.
