The one sure symptom I am aware of is spending too much time on Yahoo answers.
do you have children?
are they close in age?
do they fight?
do they get started around time for you to prepare supper?
does your husband eat & run leaving you to bath the kids
put them to bed then do the dishes& then shows up wanting sex?
those are my symptoms- i do have more but i hear baby #2 is awake from his nap-gotta go
There's no such diagnosis as "nervous breakdown." It's just a term coined by the entertainment world that seeped over to mainstream society.
If you have anxiety or panic attacks that are interfering with your life, you may have an anxiety disorder. if you are so overwhelmed you want to stay in bed all the time and can't eat or function, you may have depression. if you are hearing voices or seeing things other people don't see, you may have schizophrenia. It could be a hundred other things that make you "break down."
Please talk to a doctor or counselor today. More than likely whatever you have is treatable.
