Can I send my ballot to the Malaysian Embassy/High Commission of the country I am residing in?

No. You must send it directly to the Returning Officer of your constituency before the end of polling day.
Alternatively, seek out efforts carried out by Global Bersih and Undi18 to help you bring back your marked ballot paper.
For this coming 6PRN, you can check the details of the Returning Officer here.
