Please don't "call it quits!"
I sympathize with you and am sorry your family isn't a more cohesive support group. Uncertainty is a hard thing to wrap your mind around, and makes it so difficult to plan for the future.
Scarlett O'Hara had the right idea: "I can't think about today or I'll go crazy! I'll think about that TOMORROW!!!"
Sending hugs for you, dear lady.
