I am praying for you, your husband, and your children (both current and future).
I also am in anxious times, although I have not had an anxiety attack as you have. Where I draw comfort from is that one Scriptural quote where Jesus reassures us that the Lord knows the number of hairs on our head, so He knows what we need and when we need it.
So, things seem very uncertain right now, but your family will have what they truly need provided for them by the Lord. Jesus Himself has said so!
Now, poulaki mou, it is time to rest. Soon you will be in labor, so try to rest now.
Please let us know when your new child is born! What an exciting time!
