Oh why

Oh why is it sometimes i feel strange, sometimes i'm weary, sometimes i feel tired, sometimes i feel sad for no reason, i am quite curious why is it happen? Is there something wrong about me? Am i alright? Do i need to look for a physician? In this times of difficulties, i know there's a lot of anxiety out there, i just missed everything like those times we are not worrying about anything, having a lunch together with our friends, walking hands and hands , do cheek to cheek, if there's a silly jokes we appear together, we laughed out loud together, and there's a moment our salivas sprinklers due to laughtrip we made during breaktime, oh when did this would be happen again?
