Attention seeking methods
Attention-seeking is particularly noticeable with females so I've used the pronoun "she". Males also exhibit attention-seeking behaviour.
Attention seekers commonly exploit the suffering of others to gain attention for themselves. Or they may exploit their own suffering, or alleged suffering. In extreme forms, such as in Munchausen Syndrome By Proxy, the attention-seeker will deliberately cause suffering to others as a means of gaining attention.
The sufferer: this might include feigning or exaggerating illness, playing on an injury, or perhaps causing or inviting injury, in extreme cases going as far as losing a limb. Severe cases may meet the diagnostic criteria for Munchausen Syndrome (also know as Factitious Disorder). The illness or injury becomes a vehicle for gaining sympathy and thus attention. The attention-seeker excels in manipulating people through their emotions, especially that of guilt. It's very difficult not to feel sorry for someone who relates a plausible tale of suffering in a sob story or "poor me" drama.
The saviour: in attention-seeking personality disorders like Munchausen Syndrome By Proxy (MSBP, also known as Factitious Disorder By Proxy) the person, usually female, creates opportunities to be centre of attention by intentionally causing harm to others and then being their saviour, by saving their life, and by being such a caring, compassionate person. Few people realise the injury was deliberate. The MSBP mother or nurse may kill several babies before suspicions are aroused. When not in saviour mode, the saviour may be resentful, perhaps even contemptuous, of the person or persons she is saving.
