No, I'm not in a mental hospital. I can't really access any suicide methods because I still live with family, despite being an adult, and I can never really gain independence due to my autism. Doing basic tasks is extremely overwhelming for me and I don't have any way to cope at all as nothing really works on me.
On top of that, my parents are strict and wouldn't let me leave the house if it wasn't for a good reason (i.e. to go to university or something). Because of this, I can only really go outside during the day which makes suicide methods that require the environment in some way (e.g. jumping, drowning, train etc) be extremely difficult to pull off as people are watching everywhere and could easily stop me. Besides, the only method I can technically do is drowning as there aren't really any trains or places I can jump off near me and, even then, drowning sounds like a horrible method based from what I've heard. In addition, like I already said, people would be everywhere and, because of SI, I will end up screaming to be saved even though I know I want to be dead and, well, the rest should be self explanatory.
Also, when it comes to suicide methods as a whole, one of the reasons for me wanting to be dead is what hinders me from doing a suicide attempt to begin with. That reason being how I tend to react extremely badly to even the smallest amount of stress and pressure. I also got lots of executive dysfunction which makes planning and managing suicide extremely difficult for me as well.
At this point, I'm starting to give up on thinking about killing myself as I don't even think it's possible anymore. The pro lifers have won in keeping me alive for now... this is their checkmate
