I'm very sorry that you're in that situation, OP.
Personally I would never go for the rope unless I thought that without doing so I might end up in a situation where I wouldn't even have the option - for example, I might consciously consider the rope IF I was facing some sort of awful disease that might render me unable to make the decision and execute it at some point. I don't think there's any shame in choosing to exit, and I don't think you have anything to worry about as I believe in a resurrection of the dead, so you'll just wake up afterwards, but it's a really horrible decision to even consider, and so long as you're alive I guess there is always at least some hope that things will improve, and at least some hope to find some sort of happiness or meaning.
I think, so long as you're not suggesting damaging yourself first in order to be able to get it, that you should at least try for the SSI, though you'd have to consider the possible consequences of doing so for yourself (sorry I don't know much about the US system). I know from my own experience on NEETbux that it can be very hard to escape that situation once you've been in in long enough, and my situation has been very bad at points - but then again, I'm not sure the alternative was any better, if I'd continued working I'm sure that right now I'd just have wasted vastly more time serving other people, rather than at least having some time to myself as a NEET (even if in the end, my family stole vast amounts of it during that that time).
I don't think there's any shame in doing the sugardaddy thing so long as you don't actually have sex. If you can find someone willing to pay you to see photos or videos or something, it may not be ideal - but considering the amount of humiliation and subjugation involved in 'normal' wageslavery, I'm not sure that it's any worse. I don't see it as exploitation in either direction, but it's absolutely disgusting that people might have to reduce themselves to that rather than get support from 'society'. People in general should be ashamed for allowing such a situation to exist.
Maybe if you find a way to subsist for now, you'll eventually at least inherit your parents house if they own it? I see it as your parents having a moral obligation to support you, no matter how old, considering they brought you into the world and are responsible for your upbringing, so it's pretty terrible of them to want to toss you out.
