Am I losing my emotion?

I like being alone with my personal space i been doing it for 2 years now and i don't get excited or happy anymore like in my football team when we won i don't feel anything no Excited nor happy when i get what i always wanted i don't feel any happiness and when my parents say "I love you" i don't like it or i don't want it and when my friend's friend is dead i don't feel any sadness when someone stole my drawings and claim it its there drawing i don't get angry anymore usually i have a hot temper but now noting but sometimes (like seldom) i smile
