You can lock your emotions away. I know this through experience. I can't really feel any emotions over any matter whatsoever. But locking them up is not the way to go because you will later regret not having them with you. Take some time to recover but don't lock yourself away from everyone and everything.
If you let all your emotions go your life ahead will be very difficult.
I hope this is what you wanted to know and I hope it helps.
I say yes because I did it so can you.
It is natural to feel this condition after having some emotional disturbance in the life. Emotions are very much important to some people while there a lot of the people that don't bother what are feelings in fact. So, as you are telling that your heart has broken. I do not know what has happened to you but what ever the cause of your broken heart it is sad.
Sometimes the human being get indulged too deeply in some feelings, with your love ones, in some fantasies to be away from them.
Severe Emotional dependence on any thing is bad. Every thing in this world can not be get specially a human being. If we love some one and can not get him/her in our lives, then sometimes it can make us to think worse for ourselves. It is natural too to be almost feelingless after that because if you lose once your center of emotions, then it is not easy to get out of this darkness of depression.
You feel some thing like that in your life and that is why you are saying that you can not feel any love or pain any more. I think it is unconscious psychological reaction and you will be out of it at sometimes in your life again.
I do, my whole family does.
You shouldn't lock away your feelings I did that when I had a crush on a boy and I don't like him anyone I feel pain sometimes but never love you can but you shouldnt
Locking your emotions is a very difficult part of our lifes. But through sheer determination to over come all the lows in our lifes, we can control (lock) our emotions
