Contrary to what most people think, you don't just get sectioned just for harming yourself or threatening another, you can also be sectioned because you 'seem to be mentally ill' and therefore in the psychiatrist's mind are 'at risk of harm.'
The depot injection will damage the nerve endings over time, merely because of the needle jabbing action. The neuroleptic drugs? Well they cause your muscles to stiffen and feel restless and twitch, blur your sight so you can't read, shut down your neurotransmitters so you can learn much, or have much of a conversation with anyone etc... What are the drugs supposed to do? Make you manageable like you're some kind of cattle, or rather fruit-fly, that can't be talked to.
You can be forced to take the depot forever. It's horrible. That's when many suicide. They feel like they have no hope of escaping the pain of the psychiatric drugs and no support in the world for the person they want to be.
People are compliant with the long-acting fortnightly jab, because if they don't turn up to get it, they'll be hospitalised, put on higher doses and things will feel even worse.
The whole act looks benign, to many people. But they're not thinking of how this drug harms the person. Those who think it's benign are also not thinking of how the person is denied their opinion, as well as freedom from torturous acts, such as assault in the second degree.
People who pretends to be okay with the depot, are pretending to be okay with something very, very horrible, they really, really don't want happening. Think of the worst crimes committed on a person's body over a long period of time and the psychiatric depot inject is akin to that. Impossible, that feeling of impossible escape from a society that condemns you for thinking outside their range of understood sense, a society that picks on you when you grieve... then sends you to a psychiatrist... a society that should be better.
