Do they provide any real support after they 'save someone?'
No, not really. They're very much "catchers in the rye." They grab people and drag them away from the cliff's edge. Then they are An Hero and they are done.
In the US, you get treated like a convicted felon and you lose your right to bear arms
This usually won't happen if you sign voluntary admission papers at the hospital. It likely won't even happen if you're admitted involuntarily, provided you sort the issue out with the doctors and don't have a hearing in front of a judge. There are some pretty strict laws about what a hospital can and can't say about you and your treatment there. But once the courts are involved, your mental health (or lack thereof) becomes a matter of public record. That can have some pretty devastating effects on your life, beyond a flag next to your name in ATF's database. You certainly won't be winning any custody disputes with your ex after that. You won't be getting any jobs that require a security clearance, either. Ironically, you can probably get your right to legally purchase firearms restored sooner or later. Getting your commitment hearing records sealed is another matter. It's a civil matter and not a criminal proceeding, so there's no such thing as getting it expunged. You're never exonerated of having been mentally ill. You also aren't automatically provided with a lawyer when someone seeks to commit you, the way you would be if you'd been accused of a crime.
I can't really speak to matters outside the U.S., but here it is almost always in your best interest to sign voluntary admit papers if they offer them to you. Do your 72 hours in the hospital, complying as best you can. Swallow their nasty little pills if you can possibly manage it. If there's anything at the hospital that helps you, latch onto it, by all means. Sometimes it's it's really the other patients that provide the most comfort and hope. Sometimes it helps just to be somewhere clean and have people hand you food a few times a day. If the place is useless, just keep telling any staff who ask that you're Really Feeling Much Better Now, Thank You. They're unlikely to keep you long.
Just tossing this next bit out there because it's info I recently needed. It's a process I had to initiate ONCE in 30 years of being in and out of psyche wards. However, the spine of the U.S's healthcare system has largely been broken by covid, so I can't swear that I (or you) will never need to do it again.
If you feel like you're actually being abused or neglected, beyond "my doctor doesn't listen and the nurses are snippy," which unfortunately is every hospital unit everywhere, call the hospital recipient rights office. Don't demand to speak to a judge--it will likely take weeks before you can see one, and you don't want the public paper trail anyway. You should be given the hospital's recipient rights number when they admit you, although it could be buried pretty deeply in the stack of paperwork you're given. If the recipient rights people seem shifty to you too, ask them for the name and number of the hospital's accreditation agency. Get your ducks in a row before you call them. Write down dates, times, and names while you still remember. I'd recommend waiting to make the actual call until you get home. The accreditation agency won't tell you what actions they took (if any); you really call them to make sure the next patient down the line doesn't get mistreated as you were.
Yes, those NGOs really don't want their goals achieved because they will lose their well paid jobs.
I rather doubt it . . . human service jobs pay horribly. Sometimes job security and benefits can make such a career appealing, but you don't really get those outside the civil service sectors of well-off nations. I have absolutely no idea how people survive working at NGO's. I've done some "we r sav the wurld nao, lol" shit myself, but I've sure as hell never worked 18-hour shifts spraying down hazmat suits with bleach in some hot zone, dear God.
I read somewhere that it is Clinton but i couldn't verify the information or find out the details
Hillary invented SI? No wonder nobody likes her. Or do you mean Bill? Nvm--nobody likes him either.
