Is it better for people with depression to have company or to be alone?
Generally, whether a person with depression needs companionship or solitude should be determined based on their current state. Companionship is beneficial when they feel low and seek support, while solitude may be more appropriate when they need time to organize their thoughts. If in doubt, it is advisable to consult a healthcare professional early. The detailed analysis is as follows:

When patients are experiencing emotional lows, feelings of loneliness or helplessness, or have thoughts of self-harm, appropriate companionship can provide a sense of safety and emotional support. Family members and friends can help alleviate feelings of isolation and reduce the buildup of negative emotions by engaging in gentle conversations or participating together in relaxing activities (such as walking or watching movies). This helps prevent worsening depressive symptoms due to prolonged isolation, making companionship more conducive to emotional stability at such times.
If patients are experiencing irritability or mental confusion, or clearly express a need for personal space, forcing companionship may trigger resistance. Solitude allows them time to sort through their thoughts and avoid stress caused by external disturbances. Through self-regulation methods such as meditation or reading, patients can better manage their emotions. In such cases, respecting their need for solitude can actually reduce emotional burden and assist in gradually restoring inner peace.
If it's unclear what the patient needs, gently asking about their feelings can help understand their preferences. Avoid imposing companionship or leaving them alone based solely on personal assumptions. When necessary, adjust interaction approaches according to medical advice to better support the patient’s emotional recovery.
