“my english letter for appling to airline”,
I think this sentence would be better,
if you corrected it into ” my English letter of applying for airline”.

Anyway,
it’s a hard time to us now,
because we have to worry about our future more than ever,
but just as I usually said,
I have confidence in you, you can do it,
I wish you a good luck.

Yes, never give up!
As a Friend, I will support you and always be with you!!
Cheer up,
I hope you will have good news in you job-finding!
