restore deleted icloud music

now i'm very embarrassed

i just bought 100music on itunes store and just clear other music.

while clear other music, i accidently delete my purchased music with "also deleted this song from icloud"

and from that time i couldn't find my song from itunes - purchased tab

or no icloud symbols on my library song tab

and when i see the itunes i could see song that i bought is purchased but i can't download it

how can i do
