Hey, Tekka. I don't think I know enough about you to be all that helpful, but if you really had no feelings towards killing yourself, would you have come here to ask about it? I'm hoping that's a sign that you don't actually want to go through with it, you just want out of your current situation.
With the visual hallucinations and mental screaming, are you in counseling? If not, I highly suggest getting into that.
Death is always a "rational option," but it's not a very productive one, and it doesn't accomplish anything. It's jumping out instead of fighting. You seem like a strong person to me, and I'd like you to think of living in itself as a point of pride, so at least if you have no feelings towards death, you can have a positive one towards life, because it's certainly a struggle, and choosing to do so is a triumph.
If relationships are causing more harm than good, getting out of them would be something to work on, unless, of course, that's impossible, (i.e. if they're your family or something). Otherwise, I think extracting yourself from that stressor would be a good first step.
Other than that, I don't really know what to say, other than that I hope you are or will see a therapist or something akin to one.
Best wishes to your situation.
