I don't care about people anymore, i feel emotionless?

Depression!! See a psychiatrist and they will help you! This is serious...do it for yourself!

if you're a child it's normal ...try growing up

Honestly, I've felt the same way several different times throughout my life. I would suggest getting psychiatric help for depression because it sounds like you're severely depressed. I've struggled with depression for a long time and I'm only fifteen. Actually, I was just released from a mental hospital less than a week ago for problems relating to depression. Anyways, I feel the same way you do whenever my depression gets bad. So, I'd start with telling your parents that you think you're depressed and try to get therapy (it actually helps.)

I suffered with depression and yeah, i can say that its likely you have some form of it.

Look it up, see if thats what you have, then search for help. Some tips, tho...

-Think real hard about who you care about. There's gotta be at least one person that you really care for, even despite depression right? If they reciprocate that, remember theres always someone out there to talk to about any issues, if not a close friend theres websites like 7cupsoftea (google it) that can provide you with at least an ear to listen.

-Think hard about what you like too. No hobbie? Thats a-ok, me too, but try to think about something your passionate about - ANYTHING you like, even if its something like playing games - hold onto it.
It may seem hard to think about an individual thing because in general, it can feel like nothing interests you, but theres probably something, even if just one thing, that you cant pin point because you think of everything at once.

Holding onto things like that personally really helped me out of the worst of my depression, because at the lowest moments when i thought life was completely gray...i remembered at least one person cared for me, and i could at least feel something about one thing, it helped me think that there was colour still, even if a little, its still better than nothing.

Just think about it take 3hours with yourself it will help you

Sounds like depression. When that void takes over it's hard to find a place in your heart for others. You just get swallowed up by it.

A good first step would be to read all about depression to see if it fits the bill. And my one piece of advice is if you really think you're depressed is to realize the things you feel or aren't feeling aren't you but a symptom of depression. It can easily convince you beyond reason that there's no hope.
