Help me find this song

So probably about 2-3 years ago I listened to this song on Spotify using my Xbox. It had a pink and purple cover with the word toxic melting and there was some distortion. I remember it had the lyrics
“Let it out let it out, I don’t wanna keep it in for the sake of keeping in”
And then it said something about “smoke all the toxic”
I HAVE SEARCHED FOR THIS EVERYWHERE PLEASE HELP ME FIND IT IM BEGGING YOU
