Blimey hun, so bitter sweet for you. Sweet obviously as you're Dad will be round for longer, but also a complete head f*ck as you've mentally prepared yourself for the worse.
Go for a long walk and stand in the middle of a field and just scream if you want to, it helps get rid of all your frustration...... (check for livestock too or you may be getting some body magic too).
Failing that, just come here and talk to us, we're all here to support you x
