Yes, you do need help. You are obviously overwhelmed and exhausted in a situation that should not be exhausting at all. Don’t despair. There are things that you can do to get to the bottom of this to find what is causing your distress and how to resolve it.
You seem to feel powerless and that may have a lot to do with why you are overwhelmed. You are not powerless. There are things you can do to make your situation better.
You have said that you are exhausted from your last pregnancy and you had PPD. Are you still depressed?
You said that your boys can get out of hand. There are ways to teach them self-control. The earlier self-control is learned, the better. Yes children get loud and are energetic, but if they are out of control that is a different matter. There are ways to teach your children self-discipline that will make for a calmer, happier household.
Is your husband faithful to you?
Snow, I quoted this post because it expresses what I see in your posts here. So forgive me, but I have more questions for you.
How old are you and your husband?
You seem unable to handle a pretty normal small family. You seem frazzled and depressed. In all kindness, there seems to be something wrong.
I think you feel trapped, does this pregnancy make you feel trapped?
You seem to be fragile emotionally. Did you find things in life this difficult before you had children? Did you find being a mother as difficult after your first child? Or did all of this start with your second child.
Before you married, and then before you had children, did you have a job/career? If so how did you handle those? Was it difficult?
Some women love being stay-at-home-moms (SAHM) and they thrive. Some women do not. There is nothing wrong with being one of the women who do not do well as a SAHM. Do you think you would do better emotionally if you worked outside the home?
