How do I get through it?

Been receiving a lot of letters lately and am trying to get through them, but someone asked me, 'how do i get through it?' She lost her husband 3 weeks ago and has two young children, 2 years old and 5 months old. Here is my response to her:

I'm so sorry for your loss. and yes, it is three 'short' weeks ago. How do you do all of this...one day at a time. It's cliche but it's true. You get up for your kids and show them that life goes on. You show them that you hurt and that you get better, you show them that you fall apart and cry and then you know how to pull yourself together and do what needs to be done.

You show them how to make daddy proud.
You show them that no matter what's happened in your life you never use it as an excuse to do something bad or give up.
You show them how to survive adversity.
You show them emotions and you show them how to grieve and then you show them how to laugh and through them you get through it.
If you see a couple, you might be jealous/angry/grieving and it's normal. How do you go to the store by yourself? You take a big deep breath and go in or, if you have home delivery, you take advantage of that and go in another day.
How do you celebrate your daughter's first Christmas? It's very tough, but you give her something special. i'm sorry to say that 'she' won't remember this, but you will. Give her something special -- a framed photo of her dad or something
You ask for help and say thanks and then, when you need to, you lock the door and spend time with your children alone and you giggle and laugh because they're babies and that's what they do.
How do you get through this? With your husband's love and guidance from above, it's there.
And you know you can do it, but it's one step at a time and you do it for them and you be the best mommy you can be. And you'll do great. And it will hurt and suck and you'll hurt later on special occasions and then on other special occasions you'll be okay.
You get through this...one day at a time...with or without friends, with or without family...because you have to.
