问一句英文说法?Burning makes me sad.燃烧让我悲伤.如果要强调悲伤的程度 可不可以写成Burning makes me sadddd?我看好多人在口语聊天中都这样说 SADDDDD?

You cannot write formally as SADDDDD.
But you can do that in daily language.
Or you can do something like this:
Burning makes me T_______________T
haha
=)

desn't make any sense

那是指口语上的拖长音表达语气
如果是书面语要写：Burning makes me very/so sad.
