Hi Janet,
I saw your headline "scared to death" and I could instantly relate to you. Even though my situation is different from yours, (I am a cancer patient) I can relate to you because I lost my brother when he was only 34 years old to cancer. He was my best friend and my only brother. I too was scared because I could not imagine going on with life without him, but now it is about 30+ years later and although I still miss him, my experience tells me that the people you expect to help you might not, but help and support will come from people you least expect it from and you and your son will survive this. I didn't believe in God but believe that invisible as He is, He placed people in my life that have helped me.
Whether you believe in God or not (I got mad at God for taking my brother away from me) I recommend finding a local church and go visit the pastor during the business day. Tell him or her what you are going through. Not only will most churches take you and your son under their wings but even better, I predict that you will feel the presence of God even if you didn't believe in Him before. It happened for me, it can happen for you.
May God bless you with comfort and peace despite all the things that frighten us along life's pathway.
