Obsessive conversations or thoughts may stop, by themselves.
Or YOU stop them, realizing how bad they are making you feel.

Let me ask you something, baker: when you think that it is all somebody else's fault (your mom, your husband) are you letting out who you really are or what your Mum would say, think and do?

I guess you got yourself too tired, with the housework, yesterday and you could control less those repetitive, useless refrain: it's all somebody else's fault!! I'm just an innocent victim!!

Stop that! It takes you nowhere. You will let these thoughts out once you are with a therapist that would show what to do with thm and why you have them.

You know what Baker? You just spent the day caring for your family. You just got your self too tired and all the old patterns exploded.
Nothing really happened to make your day worse. You made it worse.

Do you really want to go on like this or better start thinking what a lucky mother you are, having 2 healthy children? and what a happy wife you are, with a husband taking care of the house income?
The way you wanna look at the world It's up to you, you choose it.

You made you own day, yesterday, cause nothing happened.
You chose to have a bad day.
Next time don't get yourself too tired, remember that you are not well and that a new baby is on the way and when those thoughts come sing aloud, force yourself to think about different things.
And you will change your day
