Molly, I remember a friend contrasting the amount of mental & practical preparation we do when a child joins the family with what we do when they leave. Endless discussion, advice, classes, books, articles and websites for new parents versus what? for the soon-to-be bereft. Lots of noise about UCAS and money. Which, I know, are important. But they distract from the emotional task.
People leaving is a Great Big Deal. Ambivalence (on both sides) is part of it, along with fluctuating denial. I wasn't kidding about my melt-down in the car park at the Bristol open day (but I had it internally so DH and DD didn't notice).
So the teenager rants about how s/he can't wait to get away from home, whilst at the same time (and no wonder) being terrified of leaving. Then leaves and wants to come straight back.
I always thought that teenage horribleness was partly a device to help them to leave home but I now think some parents (I don't mean anyone on here) need the teenager to be horrible, to cover up their own feelings of loss. God knows it will help me out if DD is as vile as my middle nephew was. (Feel free to point and laugh if that assertion is put to the test)
For me it's also unmasking grief about DD being an only child. She'd have made someone a bloody good sister & my nest wouldn't be emptying so soon. Dammit, it was only the day before yesterday I brought her home.
Sorry, not much help. Have had a couple of low days. But Our Ladies of Perpetual Succour is absolutely amazing and brilliant.
