Abgail Shrier talked a bit about this in her book. She thinks some Gen X parents in the US are sort of over-therapising some kids, like she mentioned someone getting a counsellor for their daughter because she was upset about her guinea pig dying. Therapy is really useful, I've done it and it's helped me a lot, but sometimes I think we over-diagnose or pathologise normal human ranges of emotion. The guinea pig situation is something where it was the parents job to model appropriate behaviour and you could say a good opportunity to prepare your child to deal better with grief in the future. Sending your kid to a therapist over it could basically make the incident bigger and bigger in the child's head and you are also rather out-sourcing the parenting to the therapist.
One thing I noticed over this last hellish year and a half, is this idea that you can't just feel down. You have to do something to stop it - go for a walk in nature being the frustrating go-to advice. There are times over the last year where I felt really tit, and I tried to do the 'wellbeing' stuff. I tried to go for a walk but just felt tit on the walk rather than in the house. I then decided to take another tack. Instead of trying hard to fix the feeling bad, I decided just to allow myself to feel tit. So I'd mope around feeling down and what I found is that I got the feeling tit out of the way and once I'd done that then I felt more functional. Sometimes you just have to sit with feeling crap and get the feeling crap done with rather than pushing and pushing it away. And there are times where feeling tit is a completely normal and rational response - like when you've been isolated for months on end due to a pandemic.
