I don't care. Sometimes it's good like when someone's mean to me I get fired up in the moment but when I leave the room I don't care but then sometimes I could fail a test or have something really bad happen to me and after a really short while I just can't bring myself to care
Is this normal?
I was having a really shit day
It is good to let stressful situations roll off your shoulders. If you are concerned with you lack of care you should seek professional help.
I do probably need it
That's good that you accept that advice! Please, call your insurance company and find the nearest mental health clinic near you.
