question..help!

It is a bit strange...

was + feel is not correct grammatically
and your heart 'cannot' feel tired, is you feel tried, you may say:

I feel so tried/ I felt so tired (past tense) OR I am/was so tired
I feel (felt) so exhausted

「My heart was feel very tired」當然用錯啦！你一定要用「I felt tired, I was tired」，因為這是狀態。

其實正確d黎講..i feel tired咪得咯...
如果真係一定要咁講既話..
我諗應該係 my heart was feeling very tired 掛...
