Feeling sad and depressed when someone you care about avoids you is a common emotional response. It's important to remember that your feelings are valid and natural. Here are some possible reasons why this might be happening and how to cope with it:

1. Fear of rejection: You may be feeling anxious and depressed because you fear that her avoidance means she is rejecting you. This fear can trigger feelings of sadness and low self-esteem.

Solution: Communicate openly with your partner about your fears and concerns. Ask for reassurance and clarification about their behavior.

2. Lack of communication: If there is a lack of open and honest communication between you and your partner, it can lead to misunderstandings and emotional distress. Avoidance can be a sign of underlying issues in the relationship that need to be addressed.

Solution: Initiate a calm and respectful conversation with your partner. Express your feelings and concerns, and encourage them to do the same. Open communication can help resolve misunderstandings and strengthen the bond between you.

3. Feeling of loss or abandonment: When someone you care about distances themselves from you, it can trigger feelings of loss and abandonment. This can lead to a sense of sadness and depression.

Solution: Take care of yourself and focus on self-love and self-care during this time. Surround yourself with supportive friends and family who can provide comfort and understanding. Engage in activities that bring you joy and boost your mood.

4. Prioritizing your happiness: It's important to remember that you are responsible for your own happiness. While it's natural to feel sad when someone avoids you, putting all your happiness in someone else's hands can be detrimental to your emotional well-being.

Solution: Focus on developing a strong sense of self-worth and finding happiness within yourself. Engage in activities that make you feel fulfilled and pursue your own passions and interests.

Remember, it's essential to communicate openly and honestly with your partner to understand the reasons behind their avoidance. However, if their behavior becomes recurrent and detrimental to your mental health, seeking professional help from a therapist or counselor may be beneficial for both you and your relationship.
