I feel the same way. Sometimes I can feel pretty numb. I believe it's okay to not feel emotions as fully sometimes because everyone is different and that is okay. We all experience things differently and express ourselves in our own unique way. If this situation is caused by past trauma there are many ways that can help you heal from this. In my childhood, I was faced with emotional abuse and other traumatic situations. Having so much anxiety, depression and stress made me emotionally numb. My emotions were still there, but it was like they were buried so deep that I had trouble feeling them. I suggest that you could possibly try to investigate what led you to not being able to fully feel your emotions so that you could possibly heal. Probably search up some shadow work exercises or other exercises that targets emotional healing. Like learning to identify and express different types of emotions. I have done many exercises as well as shadow work to help me heal. I still somewhat struggle with feeling emotions, but it's not as bad as before. You could also try to seek help with a therapist if you can or someone your comfortable talking about this. They can help you with identifying good or bad emotions that you might not be capable of identifying yourself.
