Bless you,
Shattered is exactly what you are. A vessel that held a husband, a future with him and your children, dreams, love, connection, assistance, etc. That vessel has been broken and you are now alone.
As a vipassana meditator I can say that this will pass. These words do not help when the pain is so great and the obstacles daunting.
My advise to you, since you ask, is to find a lot of support.
Ask for assistance and do not be ashamed of your neediness. Be absolutely clear about what it is that you need and be mindfull about who you ask to help, so that you will not receive further refusal. Remember, if you do receive refusal, it is not about you. At this point you must believe that it is all about you...not so.
Then I would say to you to take life one day at a time. When you have made it through another day, congratulate yourself. No judgement about your successes or failures. The last thing you need right now is to be refused by yourself.
Take a look at the things in your life that you can let go of.
Perhaps you don't need to make your bed, or wash your clothes, or sweep the floor, dot that last i in the paper you are writing, and don't be angry with yourself when your emotions spill over to your children. Appologize and take them in your arms to assure them you love them. You must take care of yourself or you will not be able to take care of them. This is your life now, and you are vulnerable. It is good for them to see you in your humanity...they will grow from it. Do not, however, use them for emotional support. They are your children, not your caretakers.
The pain will be there for a while and it will go away when it is ready. Simply acknowledge that it is there and it will soften.
Good luck, sister, this life has many offerings to you, some desired, some not. Our pain comes in craving for things and in pushing the things we don't want away. Simply being aware of what you feel will soften your life.
