busting a try hard

A person who try's so hard they always get put down or in a bad place.

For example: A female who has been in a relation ship with a male for long time and then he leaves her for a younger girl and after she gets back with him and gets cheated on by him and she still secretly messages him non stop because she still loves him while she is also in love with his friend but neither like her and both use her. Therefore she try's to hard for a man and is busting a try hard. Can be male as well or anyone trying way to hard
