Yesterday I categorized all my blogs.
Due to which there was not a single blog in the Categorized i.e default category. Today in the morning when I checked all blogs from last 3 months were deleted even from trash.
I do not how because I am only one with admin access. Can I know the reason how the blogs are automatically deleted?
Even from trash.

I assume you mean blog posts and not blogs which usually refers to all posts together.
Anyways, it sounds like a database issue, not a WordPress issue. WordPress will not automatically delete posts.
You either have some bad acting code on your site (like a plugin that's doing far too much), or much more likely, your site's database (or the posts table) was restored to an earlier date or emptied entirely.
Since you are still able to log in, we can rule out that your database is gone or that the entire database is reset. It may still be the wp_posts table which holds your posts.
You should restore your most recent database backup and go from there. If you are not making database/site backups, you (a) need to start and (b) should contact your host, because many (most?) web hosts make automatic backups and may be able to retrieve a recent one for you.
Do that today -- time is of the essence -- because generally automatic backups are only kept for a limited amount of time.
