Your propane company should have an emergency number that you can call. My sister gets propane and she's on a regular scheduled delivery and doesn't have to call them. You need to find out about that instead of running out all of the time. Some of the nights are going to be cold by the end of the week. There is even talk of some areas getting snow Friday/Friday night. Please be very careful w/those space heaters.
What you posted about your feelings is very normal. You are going to continue having ups and downs for a long time. It's not over until the fat lady sings and she's not been on stage in quite a while. No one knows for sure how things will turn out. All you can do is plan for the worse and hope for the best when dealing w/people in crisis.
I do hope that you have a good evening.
Happy New Year!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
