Lost Facebook and Yahoo mail accounts

Windows upgraded me to Windows 10 and cause me to lose both my Yahoo email account and Facebook I used the same password .
Facebook claimed I changed my password last month I did not change it.
I had to get a new email account to get back on Facebook they sent me code number and I was back on however they soon block me accusing me of pretending to be someone else however I used my own name Janet Bosley and my own quote in my cover and I used the same profile photo .
I also sent them pictures and my phone number and my complete mailing address.
I cannot check my yahoo email nor get on Facebook nor click on windows to clean my disk,set my clock there is a small little blue circle that covers all icons on the bottom of my screen .
Windows made a mess and I need my yahoo email and my Facebook accounts restored .
