Do yall ever just feel empty or is that just me

Ik this might be a weird question but sometimes I just genuinely feel this way like sometimes I feel happy and sometimes I feel sad and sometimes overwhelmed etc. like emotions yk but then sometimes I feel nothing like blank and numb or hollow is that normal?? Like I could be so fawking silly for one second and then then a few minutes later blank no emotion just hollow erm..😭😭

(idk what category to put this in heh...)

ALSO TO CLARIFY IM NOT CRAZY OR ON DRUGS OR DEPRESSED OR ANYTHING I JUST FEEL THIS WAY EVERY FEW WEEKS OR NOW AND THEN
