Virtual handhold here - from fellow single parent. It is so tough being strong at such times - bad enough when they fall out with their friends - but self-harm really hard (but also very common) and yes, as some have said teenangers can be brutal.
Good that discharge has happened - things put in place. Time to cling to each other - wrap yourselves up in duvets - watch films etc. Fruit smoothies maybe useful to order in or maybe flavoured Kefir if stomachs fragile (and that is both of you, you've had a dreadful shock - and we do tend to blame ourselves - as parents, please don't).
And you will still have a lot to do to put plans in place as single parent I know.
A few things that might help - it is June so school year nearly over for most of us - makes sense the plan that previous poster has said about home schooling. Although I do know of a friend whose daughter went through this - and their DD wanted to go back to school - after certain things were resolved.
Either way - you are probably rushed off your feet but perhaps contact the Parents Helpline on Young Minds. 0808 802 5544
9.30 till 4 monday to friday.
They also have a webchat.
Also this book
www.amazon.co.uk/Cope-When-Your-Child-Cant-ebook/dp/B0962XFG2J
'How to cope when your child can't - hope and comfort for parents'. don't know if this book is on Audible it might be.
You will get through this stronger. As tough as it is - going forward it means you will be talking more about mental health which as every single one of us needs and there should be no shame attached to that.
At the cinema yesterday I watched a hard hitting ad from Campaign Against Living Miserably - with videos of people who seemed to be coping on the outside but weren't.
We all need to talk about it. Parents and Young People have been put under such pressure in the pandemic. Single parents even more so. I've said to my DD many times I don't care about results - we'll just try to get through with mental health okay. That's the main thing.
Hold each other close eh.
Virtual hug
