Honey, be patient with yourself. Mourning and grief take their own time.
Give yourself the gift of minimum standards until you feel in the groove of things again. For example: you may decide that everyday, no matter what, you'll have a made bed, empty sink (which doesn't even mean the dishes are done, but that you have full unobstructed access to your sink), the floors swept and/or vacuumed (maybe in just one or a few stratigic rooms), and some sort of extra easy dinner for the day. As a Mom; tell yourself at least one story for the children a day that you read. Set your minimum standard and strive for those few things allowing yourself to feel like you accomplished the day...if you do more then that is BONUS!
We like to jump back into our old lives, but we can't. Everything is a new normal.
I suggest getting the book, "Gone Too Soon".
Here's a link to Amazon:
http://www.amazon.com/Gone-Too-Soon-Infants-Children/dp/1...
If you scroll down a bit you'll see that it's frequently purchased with 2 other good books, "We Were Gonna Have a Baby, But We Had an Angel Instead" and "Mommy Please Don't Cry: There Are No Tears In Heaven"
Now some people may say silly things to try to make you feel better or put you back on the path of "normal" so they don't have to face the pain you may be feeling, but that doesn't change the fact that you need to nurture yourself...you need to be gentle with yourself...and you need to allow the normal course of greif to flow. Let yourself cry, let yourself be angry, let yourself be disappointed; Choose a time in the day when you can lock yourself in your room or bathroom or be with a friend where you can let it all go and then make room for your happy feelings about everything else bubble up.
Get a notebook that you can write, draw, scribble, doodle, and color in. When you're feeling overwhelmed, or UNDERwhelmed, stifled, empty, angry, sad, confused...basically any time...open it up and release yourself to that paper. Words and functional or proper sentences are NOT important...the release is. Your notebook is always available to you no matter what time it is, has no feelings that you should be over anything or that you should be holding onto anything. Just take a few minutes and RELEASE. Crumple the paper, write random words, stab the paper, scribble random colors, draw stick figures, write letters, create poems and songs, draw beautiful scenes, draw dark and angry things, swear, pray, encourage, plan, be grateful, list things to be thankful for, list things you're good at, record quotes you like,...just RELEASE onto the paper. Keep it as a reference for when times are better and/or someone you love is going through the same journey--you can share it if you like for honest and credible empathetic advice.
Remember your husband, too, is likely sad. He, too, probably feels uncertain but is trying to be strong and pretend everything is normal. Men do that. They fake strong and unchanged as a protection for themselves as part of their way of protecting you. Unfortunetly, they sometimes use anger and short tempers as a disguise for their sadness because "men aren't supposed to cry". Some men are more open and sensitive while the woman tries to be stoic. I mention this, because in grieving together it's very easy to allow the other person's style to offend the heart. Make it a priority to allow affection and connection with your man. This is important for your unity; scientifically, for your body to produce oxytocin and endorphins which raise your positive feelings. Dark chocolate will help, too. :)
It's very important you get proper nutrition, sleep, and hydration. Sometimes we don't want to eat and feel like we can't sleep during times like this, but you must be extra careful about tending to your body. I would suggest getting a superior suppliment (of course, I suggest SHAKLEE)and protein drinks to assist in this, especially since we tend to lack the desire to eat well--or at least, cook well.
It is impossible to be unchanged by this. The "myself" you may be looking for could be gone forever...the New You, may be better...allow that to be true and you'll find peace.
