Certain people may give you anxiety for a variety of reasons. Here are some possible explanations:

1. Past experiences: If you have had negative experiences or conflicts with someone in the past, you may associate them with feelings of anxiety and worry about potential future interactions.

2. Personality clashes: Sometimes, people's personalities or behaviors may clash with yours, leading to increased stress and anxiety in their presence. Differences in communication styles, values, or attitudes can contribute to feelings of discomfort.

3. High expectations: When you feel pressure to meet someone's high expectations or fear judgment from them, it can trigger anxiety. This may occur in the context of a superior, authority figure, or someone whose opinion you highly value.

4. Power dynamics: If you perceive an imbalance of power or feel subordinate to someone, it can lead to heightened anxiety. This could be due to a hierarchical relationship, such as a boss or teacher, where you fear negative consequences or criticism.

5. Lack of trust: If you do not trust someone or have doubts about their intentions, it can create anxiety. A sense of uncertainty or skepticism about their motives can trigger feelings of unease and anxiousness.

6. Social anxiety: Some people may give you anxiety simply because you struggle with social anxiety in general. This can make social interactions challenging, and being around certain individuals may amplify this anxiety.

It is important to remember that anxiety can be influenced by a combination of factors, including personal experiences, perceptions, and individual differences. Seeking support from mental health professionals can be beneficial in managing anxiety related to certain people.
