losing friends without feelings

today i lost a friend,a really good friend. we got bullied by the same people and always talked to each other about it. idk when he because the people who bullied me but he did. i always thought no matter what he’s be my best friend, but here i am, without him. when we got into our fight today i didn’t feel sad, upset, or angry. i felt nothing. and now that i look back i haven’t felt anything, happy, sad, excited, pain in a really long time. is that normal?
