A big hug to you I know you have a hard time now, because you are the type that takes on all problems before they arise.
My wife was such a type for a long long time and true self-developing she has managed to get rid of it.
It is hard for you and it is very hard for your surroundings that will see how you suffer and that might see your problems a whole other way.
You are about to suffer for 1 year in thought that you will not manage to keep the house you will receive then.
By doing so you might be ill on your nerves...and you might due to this get your worst thought fulfilled, you loose your income and you get your confirmation.
But what if you instead put up goals...start a saving program that not are to hard....it must be possible to maintain....make yourself look forward to new home..make dreams....but dreams you know you can afford....the main thing is that you keep a positive thought...suppress all thoughts about not managing...this will give you and your family a much more calm and harmonic situation....it will also lead to a higher working capacity for you...because you now work toward something positive...not only for avoiding something negative.
It's funny....both things say work more....but our brain is funny...if we work to avoid then negative...our thoughts make the work hard and we have nothing that can ease our burden....if we on the other hand work equal much...but we have a positive goal....then our thoughts give us pleasure that allow us to endure more....since we are in a positive state our surroundings will also give positive impulses and life might feel much easier to live
Another big Grandpa hug and a big hope that you will have your own home soon
