I've booked to have our old back boiler removed and replaced with a shiny new combi next week plus a system flush - I've never had work men in before, everything we have done to the house we have DIYed.
I feel stupidly anxious about the whole thing, how much mess will it make, how do I not appear like a weirdo, how do I interact with the boiler men without my dad there.
I'm nearly 30 with a toddler and a baby on the way but this has made me feel like an incompetent flailing child 

Can anyone else relate or am I a total weirdo
