CAMHS was under immense pressure, but a waiting list that has grown by 12 months is a service that's gone from just about managing with an already too-long wait of 6 months to one that's barely functioning. CAMHS did not stop functioning where I work though there were fewer referrals, it was remote and phone work for all but those in crisis, then when schools went back in Sept 2020 referrals went through the roof.
It's not about coping skills per se, it's that young people were denied what they needed for their development, being with other young people, navigating the increasing demands of school and their relationships with adults, structure and predictability as well as the pleasure in play, exploring identity, having a laugh. Some of those young people had parents who died or who were CV and worked throughout the lockdowns. For some its been temporary and they've got back on track more or less, for others more vulnerable, it's been catastrophic, so young people with underlying difficulties that affect their learning, difficulties that would have been picked up by school by the end of year 7 or beginning of year 8, are now in crisis in year 9, or even later in years 10 and 11.
