It's important to remember that emotions and reactions to events can vary greatly from person to person, and there is no one "correct" way to grieve or express empathy. People process emotions differently, and it's not uncommon for individuals to have varying responses to situations like funerals.
It seems like you have a different way of coping with emotions and expressing empathy compared to your mother or others around you. It's essential to recognize that this doesn't necessarily mean there is something wrong with you. People have different coping mechanisms, and some may find it easier to compartmentalize emotions while still showing support in their own way.
Crying or not crying at a funeral doesn't determine the level of your empathy or care for the person who passed away or their loved ones. Sometimes, individuals may feel the need to prepare themselves emotionally before such events, which could affect their immediate emotional response.
However, if you find that your emotional response to failure is causing significant distress or feelings of worthlessness, it might be helpful to talk to a mental health professional. They can provide you with support and guidance to navigate these emotions and help you develop healthier coping strategies.
Remember, seeking help from a therapist or counselor does not mean there is something wrong with you; it's a proactive step towards understanding yourself better and improving your emotional well-being. Everyone can benefit from professional support at different points in their lives.
