Word for someone who always seeks appreciation for his deeds or work however small or trivial it may be. If they don't get it, they will be vocal about it and ask point blank like for example "Isn't this good. You didn't say anything about it."
Here the person may not have an inflated sense of their own importance like a narcissist, but they always seek appreciation. They go into depths of detail about what and how they have done mostly to sensationalize how difficult or tough the job was so that they can get some appreciation.
