谁能为我用一段英语拒绝别人?他用英语告诉我,兄弟一场不应该为小事生气,还说要请我出去吃饭什么之类的废话..不想理他,我想用英语回复,谁有更好的句子,字数大概在30之间,最好!好的,多给

Thank you for inviting me out for dinner.However,I am not feeling well recently.I really need some time to be with myself,and thank you again and maybe next time.
(Hey,I would not agree with you.Brothers should understand and take care each others.)
