Hi Michelle,  I noticed you have joined the Online grief support and I wanted you to know that I am so sorry for the loss of your fiancé.  The loss of the love we had wanted to have forever in our arms is now having to take repose forever in our hearts.  I am positive you are having a hard time with his absence but I will tell you a couple things that might help.  

One, take baby steps.  You will find yourself only being bale to do a couple little things a day while you are in the shock of his death.  That's ok. Its what we all do.  Baby steps.  Any step is a victory. 

Two, I am much older than you and did not have children but I believe if you focus on them ( i had to use other things) you will find enough distraction to help you get through the day or at least a lot of it.  Distraction is key.

Three, if you fall, get up.  If you fall again, take a rest but get up again.  You know what you have to do and it will be everything you can do to accomplish it but it is what we are stuck doing.  We come here to lean on each other and support each other.  Do that instead of anything else that may seem appealing.  read, write when you want.  No one here judges.  We just talk because we need to.  We understand because sea re experiencing the same hurt.  We all gain insight and get up again and take another baby step.

I just wanted to acknowledge your presence and I hope anything I said will help.  W certainly all know we need help to walk this path………take care.
