The feeling that "everyone hates me" often stems from internal thought patterns and emotional states rather than reality. This feeling can be caused by cognitive distortions like personalization (assuming others' actions are about you), low self-esteem, struggles with mental health such as anxiety and depression, being around unsupportive people, or highly sensitive personality traits. Social media comparisons and physical or emotional exhaustion can also contribute to this perception. Moreover, humans are evolutionarily wired to be sensitive to social rejection, which can amplify these feelings even when they aren't accurate. Key reasons for feeling like everyone hates you include:

• Personalizing others’ actions and overinterpreting social cues negatively.
• Low self-esteem projecting internal self-criticism outward.
• Mental health issues like anxiety and depression causing negative biased thinking.
• Being around the wrong people who may not treat you well.
• High sensitivity to perceived rejection or criticism.
• Physical and emotional states influencing perception.

It’s important to remember that this feeling is often a distortion and not the truth of how others actually think or feel about you. Techniques such as examining the evidence objectively, challenging negative thoughts, and seeking support through therapy can help shift this mindset.
