Ida,
There is no good time to get used to a new OS. As XP has become a target for people that want to hack your computer, if you depend upon it, the right now is the best time to get used to a new OS. Windows 7 (which you can still find around) is not that dissimilar to Windows XP. Windows 8 and 8.1 are a different story. I understand the temptation to keep with XP. But if you care about your data, computer fraud, and identity protection you really need to switch. Think of the destruction of your old computer as divine intervention. Good Luck.
