you are grieving for your old life. its NORMAL! please, allow yourself the space and time you need to grieve over the loss of your job, your friends, your responsibilities, your usefulness, and then...SNAP OUT OF IT!
God closed a door, but he opened a window. You have new friends, new responsibilities, and new road to travel. You can actually get stuff done in YOUR house, instead of taking care of everyone elses. Take the time to garden, smell the flowers, take a walk, sit on the porch, watch a good movie! As you adjust to your new life, you will find that you are going to be amazed at just how much was being asked of you in your old one. You have earned the rest. Nap!
