i do not know exactly what may be going on in ur personal life or what you may be thinking or what even led up to this almost numb feeling but i can try and maybe bring up a possibility.
stressing on the word "possibility"
you may not be in pain but i can only assume you're not particularly enjoying existence either. and not enjoying or at least being content with being alive, even if it doesnt really effect you as much as you think it should, kinda has the same effect as someone who is in pain. you may still feel like there isnt really anything here that's new or exciting for you. which is a thought that many people here have.
don't feel like you're mind is broken because you don't feel the pain you might think you should be feeling. everyone processes things different ways.
i don't know if you have suicidal ideations or not, but in the chance you do, the thoughts you may be thinking are valid, even if you arent noticably upset. life can feel mundane, tiresome, maybe even "why am i still doing this?" but as a genuine question and not from a place of sadness.
whatever the causes may be though, i hope you are eventually able to make sense of it.
sending love <3
