I've been through that yes. In the US we call it a court order but it's the same outcome. You can't refuse treatment and they don't listen when you're being hurt.
I tried to tell them the drugs they were giving me were making me so sick and increasing the torture I feel inside, increasing the hallucinations and all that and they responded by raising the dose and making me even sicker.
It sucked so so much, I wanted to die. I was able to spit out some of the pills, but it was hard to do with them there watching and checking. They also have injections so if they catch you doing that they just start giving you injections instead
I'm sorry this is happening to you. Just keep communicating what is happening and what your desires are. I don't know the law there so can't help you on that, but if it's anything like here you really don't have any choice and probably won't be heard
