Reid commits suicide it's all very sad

Hello there!
I read a fic a while a go (maybe on ao3 but i checked the suicide tag) about Reid who commited suicide. He leaves the team gifts and trackes down gideon to send(?) him one. I'm pretty sure Morgan gets some books. Reid commits suicide by OD or drugs of some sort which he injects himself while in bed. Morgan is very sad. It's all very sad really.

Anyway if you know where to find it it would be great;)
