You will be just fine...all these thoughts you are having are very normal and most of us have wondered too, how will we feel? How will we be? Can we pull this off? Will my family still love me if I'm bitchy or different?
If you have your hubby so support and you are honest with the kids.....that's what you need. If other family members get judgmental or nosy...shut the door on them. You need to take time for yourself to get thru this. You can be selfish. I told you this is like major illness. You may recover better than you think. The stories here are sometimes horrible...sure, there are really good ones but the bad freaks peeps out!
So....just go with the flow. Don't worry, many of the issues will disappear over time.....and some funny ones do come up....tell hubby to watch out as you might jump his bones quite often in the weeks to come! Libido comes roaring back for most people.
