I don’t mean actively trying to commit suicide or being careless and stupid, you know, just feeling like if I woke up tomorrow and said to me, “Oh hey, like, you died last night” I wouldn’t care.
Is this something serious? Should I seek help or consulting?
Nah, we all come to terms with our mortality in our own ways. It doesn’t always stay the same, just to warn you, but reaching a point of accepting death as part of existence is not a problem.
Now, you may or may not also have some issue influencing this, but there’s no way to know that from here.
