Monica is right, no one will know for at least 100 years, in fact the 1921 census will not be made public until 2022 so more than 100 years. If you are concerned about your grandchildren finding out maybe you could do a little autobiography for them. Don't know how old you are but I've been down as employed on various censuses since 1981, and they will as they become available show my life to anyone interested in 2081, as will my life and parents in the decades before that
So if you for example worked your way up through the legal ranks and ended up as a high court judge, they will find out about that first, and only in 100 years that you then became a cleaning lady, which is an honorable profession, I've done that at times, and if you had written what happened they will understand.
I'm sorry that it has brought up bad memories for you, but this is going to happen from time to time, people asking about your life, far better to get help coming to terms with it, any injustice is hard to cope with but it can be good to not be so upset every time you think about it.
