How can I get my accounts back ?

Ask lestermount..............

 You dont need em Christina yahoo answers is closing down very shortly.

you can try appealing but yahoo doesn't respond to appeals anymore, so that's a waste of time these days. 

So in other words, there's absolutely nothing you can do these days, except start over. 

Need more info.. for a proper answer..

If it has been more than one year you won't be able to get it back. It no longer exists. Yahoo accounts are deleted after 12 months of inactivity if they aren't used in that time.

I don’t know.
