A man falls in love with a girl in some picturesque landscape. His love seems to be mad and devoted, but he does not have a courage to confess it to her. He tries to tell her about it but It's too difficult for him to say it directly. However, finally she figures it out. In fact, he is completely indifferent to her, she doesnt feel anything towards him, he is just a person she knows a bit and nothing more. She is embarassed and irritated with the thing and what she wants from him is to do what he has to do and then get off her back. So she tells him he should just express his feelings, take his actions directly and not prolong this awkward situation any further. "If you're gonna kill yourself then do it" means "just do what you want to do, it won't change my attitude".
