I am in need of help in finding a fan fiction that has been on my mind for awhile now.

What I remember is that John catches Dean with drugs. It's set in a park that John told Sam and Dean not to go to. He reacts badly and knocks the stuff onto the ground. Dean cries out and tries to gather what is left. John is shocked at Dean's reaction. Dean had too much pressure on his shoulders while looking out for Sammy and that's why he was doing the drugs.

Any help would be awesome! Thank you :)
