weepy day

Kathleen
Emotional person here.
I'm 29 weeks pregnant and today was the first day I was this weepy! Anyone else felt like this...feel like I have weight of my world on my shoulders yet everything I'm worrying about isn't that bad.
My daughter is 8 and got the chicken pox the other day...I've had it but still worried I might catch it as had to get a blood test.
Also my daughter has autism which due to her hyperactivity levels I am struggling to cope with the extreme tiredness while she's been off school due to the pox.
Anyone had this head tightening feeling???
