Total overload

Katek speak to your family, especially your DH, about how overwhelmed you are getting. See what they can suggest to help.
You should definitely try to get to the dentist, as a dodgy tooth can poison your system and drag you down, until you get it sorted.
Please don't keep trying to struggle on with everything.

Oh dear hun you are seriously overloaded. Is it possible to delegate anything? I know it's probably not because I used to be an overloader and it's difficult to get help.

As regards to the Montolukast. Take it. Our son has it and it's very effective. It helps to suppress the bodies reaction to allergies.

Sympathies. It has horrified me that for the last year or so, when it is family birthday time, Christmas, Easter, my reaction has become one of frustration and irritation at the extra effort involved in stepping up to meeting the pressure I feel. This year, we've agreed on a family Secret Santa and everyone's happy with that and has agreed we'd rather have a nice time together and forget the buying of stuff that, for the most part, no one really needs.

I get ill when I'm stressed. I daresay you do already but do you take extra vitamin C? I've been a fan of Redoxon for years when stressed, sometimes I buy other formulas of vitamin C. They do give me a lift and my immune system a boost.

Sounds like you have got an awful lot on and the SIL rugby injury must be a real worry.

Do try to rest, easy to say, hard to do. Even taking yourself off to bed for 15 minutes and listening to a podcast etc (what I do) can make all the difference.

Crikey katy you sound as if it's a case of "drowning not waving"! You're going to have to let some of it wash over you ... and delegate!
