DD (5yo) is incredibly anxious. She started school this year and the beginning of the year was ok but over the past few months her behaviour has deteriorated.
She has tantrums now that involve hitting, kicking and head butting. I have tried a great many approaches to this and am now just cuddling her until her temper subsides. (I still outline the boundaries clearly and it can take quite a long time for the tantrum to be over because I do not give in.)
She is now suffering from separation anxiety from me - complaining and crying when I leave for work in the mornings (3 days/week) or not wanting to let me go when I drop her at school.
She has never been totally dry overnight but now she wets the bed every night (she's back in pull-ups) and has started wetting her pants sometimes in the day time (ie not making it to the toilet in time, not making puddles but becoming noticeably wet).

I spoke to our GP the other day who agrees that the issues are related to anxiety. This could be because of school and also my mum is very ill atm and I am getting upset from time to time. Also we haven't been seeing her as much as we used to because the illness and the treatment make her incredibly tired and her immune system is suffering. I have spoken to Nat a bit (very simply) about how Grandma doesn't feel well, feels very tired etc but haven't gone into anything in depth. Nat doesn't talk about it, doesn't indicate that she even thinks about Grandma being sick. She also doesn't talk about school in a negative way - she genuinely seems to enjoy it.

I am not sure how to resolve any of this, or how to work out where to start in addressing her anxiety. The GP's suggestion (apart from a urine sample to check for UTI) was loads of reassurance and positive reinforcement. The GP is not worried about nocturnal enuresis in a 5yo as she says this is a development issue that will come in time. If she is not dry overnight by the time she's 7 we will look into alarm systems.
But after leaving for work this morning and having her desperate for me to stay, and according to DH she cried rivers when I left, I just feel so hopeless and I want to help her. If it were your child would you look into professional help? Or should I just persevere with reassuring her as much and as often as I possibly can?
