HERE, if anyone still believes I need therapy for asking, here's the "diagnose" researchers have done.
Insecure attachment models in childhood most likely lead to insecure relationships in adulthood:

"Highly anxious individuals [those who had an insecure attachment model, where parents didn't satisfy their needs and made them feel unworthy] are heavily invested in their relationships, and they yearn to get closer to their partners emotionally to feel more secure. Anxious individuals harbor negative self-views and guarded but hopeful views of their romantic partner. These conflicted perceptions lead anxious individuals to question their worth, worry about losing their partners, and remain vigilant to signs their partners might be pulling away from them. Thus, they are motivated to increase their deficient sense of felt security [12], which leads them to act in ways that sometimes smother or drive their partners away."


"when highly anxious people encounter internal stressors, they perceive their partners and relationships more negatively and behave in more dysfunctional, relationship-damaging ways."

(Jeffry A. Simpson, University of Minnesota and W. Steven Rholes, Texas A&M University).

"Anxious Preoccupied Attachment – People with an anxious attachment tend to be desperate to form a fantasy bond. Instead of feeling real love or trust toward their partner, they often feel emotional hunger. They’re frequently looking to their partner to rescue or complete them. Although they’re seeking a sense of safety and security by clinging to their partner, they take actions that push their partner away. Even though anxiously attached individuals act desperate or insecure, more often than not, their behavior exacerbates their own fears. When they feel unsure of their partner’s feelings and unsafe in their relationship, they often become clingy, demanding or possessive toward their partner. They may also interpret independent actions by their partner as affirmation of their fears. For example, if their partner starts socializing more with friends, they may think, “See? He doesn’t really love me. This means he is going to leave me. I was right not to trust him.” (Lisa Firestone Ph.D.; "How Your Attachment Style Impacts Your Relationship"in psychology today)



See? People study certain behaviors. That's how we make sense of the world that surround us.

I'll continue my studies.
