DS texted me on Friday Are you at work? I need help.
I panic text back Ring Me
DS: Nah. Email
I wait for his emergency email needing this help ... and wait... and wait.
Eventually i ask What's up? Are you OK? I'm worried.
His reply I'm fine
That was Friday. The bugger hasn't been in contact since. 
I'm finding it so hard not to try and helicopter parent via text.
