My favourite person wants me dead

My favourite person wants me dead. I poured my heart out to a guy I met 2-3 weeks ago, he seemed like he liked me too, we told eachother we love eachother, telling eachother that we'd do anything for eachother, until now,

He told me he wish I'd get assaulted and killed, hoping I died in my sleep. Calling me a faggot, and a whore, and that I mean nothing. I've never felt more hurt in my fucking life I can't do anything but cry now, all of my time wasted on someone who wishes I never lived, I feel so empty, and numb, I don't know what to do.

I might as well kill myself, right? I have no one else to live for, I've never had anyone romantic in my life, besides this one guy, and I don't know what to do now that he's gone.

I don't know what I'm doing anymore.

Edit: I've come back the next day, and had realised there is a large lack of context. I was in a depressive episode, and did not expect my post to gain so much traction.

" You only knew him for 3 weeks, why does it matter? " I am a very clingy person, I don't have many people in my life, so once someone starts to show any type of love, being romantic or platonic, I get clingy, I feel like I can only rely on them since they love me.

The age gap: Our age difference is 4-5 years. I am 14/15 whilst he is 19/20.

Hopefully this clears up any confusion
