Two and a half years ago my grandfather passed away and we had a special connection( he always called me special k and i hung out with him a lot) and ever since then i've been confused and scared. Whenever i try to talk to my parents about it they say it's just puberty but at nights i cat stop thinking about it to the point where i'm crying and I'm barely getting any sleep. I just want to stop thinking about it but every where i look there's something that has to do with death, in songs, shows, talks, everything. Please help me, i just want it to stop.
