Sounds quite tough situation to get yourself do what you wish for. Terrible fate and I feel sorry for you for that. I hope I can assist you.
First I must ask you: Are you absolutely sure you can't do a thing at home? Aren't there wardrope poles or doorknobs/handles that you could use for partial hanging f.e.? There is also a night night-method which works identically to partial hanging (pressing the carotids in the neck) and requires minimum amount of money and doesn't even require a doorknob/pole for environmental support. I don't know are there other reliable/easy/cheap ways too (I haven't skimmed through/read carefully all the methods here on this website) you can do at home but there are resources listed
here.
If you're always accountable of your goings and your location, you can always lie you have some other businesses to do like going somewhere shopping something nice/necessary f.e. groceries etc. and instead of doing only that you can go to purchase rope for partial hanging/ratchet for night night-method. Or perhaps I've understood something wrong and that you're always under heavy surveillance like GPS monitoring or something and that they examine you every time you get back to your home. Hope this isn't the chase because then I honestly don't know what to do.
Do you have any of these nearby where you live: deep bodies of water, railroads or high spots (buildings/cliffs) without unsurmountable barricades/blockades/fences? These are always a plan B option if you are provided with these favorable environmental and infrastructural factors in your vicinity and have access to them.
Hopefully I understood your situation correctly. And if I wasn't helpful/I misunderstood something, I sincerely apologize. I hope you will find a right advice to a path you've chosen.
