Suicide thoughts (sterek)

After the nogitsune stiles was never the same. Deaton warned him about the dark effect that he would never be able to get rid of, that it would always be there in the back of his mind which stiles understood but didn't pay much attention to.

Everything was fine for a while until he started to get more depressed, more anxious,more unhappy with his life and more angry.

He tries to do some stupid things, some things that would end up being devastating if it weren't for his saviour, Derek.

Will Derek be able to help stiles in the way he needs and will they both admit the obvious feeling towards one another or will that just end in more hurt and devastation?
