Histrionic personality disorder - this is probably it. Does this sound like you ?

Histrionic personality disorder

You have a personality disorder characterized by a pattern of excessive emotionality and attention-seeking, including an excessive need for approval and inappropriate seductiveness, usually beginning in early adulthood. You are lively, dramatic, enthusiastic, and flirtatious.

American Psychiatric Association

You may be inappropriately sexually provocative, express strong emotions with an impressionistic style, and be easily influenced by others. Associated features may include egocentrism, self-indulgence, continuous longing for appreciation, feelings that are easily hurt, and persistent manipulative behavior to achieve your  own needs.

Characteristics

You are able to function at a high level and you can be successful socially and professionally. People with histrionic personality disorder usually have good social skills, but they tend to use these skills to manipulate other people and become the center of attention.^[1] Furthermore, histrionic personality disorder may affect a person's social orromantic relationships or their ability to cope with losses or failures.

People with this disorder lack genuine empathy.  You start relationships well but tend to falter when depth and durability are needed, alternating between extremes of idealization and devaluation. You may seek treatment for depression when romantic relationships end, although this is by no means a feature exclusive to this disorder.

You often fail to see their own personal situation realistically, instead tending to dramatize and exaggerate your difficulties. You may go through frequent job changes, as they become easily bored and have trouble dealing with frustration. Because you tend to crave novelty and excitement, they may place themselves in risky situations. All of these factors may lead to greater risk of developing depression.
