I'm at my wits end, I really really I am.
He's just weed in my display cabinet.
He can't just talk to me, everything he says has to be shouted.
If he wants something doing he'll shout " Help! Help! Help" at max volume until someone comes (I tried ignoring him once for 90(!) minutes, but unfortunately I gave in first, people were walking past and looking in
)
He shouts over me if I stop to chat with anyone.
He can't just walk anywhere, got to run, he's always bumping his head on the doorframes because there is just not room for fast running in the house.
He wakes every 3 hours!
I'm exhausted.
I want to run away 
His dad is working abroad and was due back this month but will now be another month, so no time off from him. He's at nursery, but the walk home with him is traumatic in itself!
(He was acting like this before XH went, just getting worse, or I'm getting less patient)
What do I do?
I'm a crap mum aren't I?
