What do I do now?!?!? [TW: SUICIDE MENTION]

I've contacted suicide hotlines twice now. They help, but I don't know how much longer I can hold out anymore. I feel like I'm a burden, I feel like I'm annoying. I can't even open my mouth to talk anymore. I can't even think some days and it hurts my head. The feelings are still there even if I don't think. I feel nothing but sorrow. I want this to end. Please help me...
