Advice? Please

TW: mentions having su!c!d@l ideations, mental hospitals, etc.

So my friend called the police on me a little over a week ago because they were concerned about me having suicidal ideations, I've said a few times that I wanted to commit, but I haven't done so recently. Anyways, they had checked up on me because my bio (we were having this discussion on ***) said that 3-12-23 (my next upcoming birthday) would be my last day. I kept telling them I was okay because I didn't want anyone to worry that badly about me, and they kept insisting I tell them what was wrong. I refused to so they said that they should call someone since I'm 'oh so okay', and I was thinking that they were going to call one of our friends who they'd think I'd tell whether or not I was okay, so I went on a rampage texting all of our friends saying how if they were to call them and ask if I was okay, they'd tell them yes. I get on VRChat due to boredom, and about 10 or so minutes later I hear banging on my door, and then 2 minutes later my mom tells me to change because there are some people who wish to speak with me. I say okay, and I walked downstairs to the front door to see 3 police officers outside. They told me they received a call from someone who claimed that I was thinking of committing su!c!de. I told them that I haven't had suicidal ideations for a few months, nor had I hurt myself. They said that the person who called told them the same thing and then brought up how I had been planning to commit on my birthday. I denied all of what they said, and they told me that I should seek professional help, and go to the local hospital for a mental health diagnosis. I denied it and went back inside after telling them I didn't need help. A few minutes later I go back down, and my mom tells me that she was going to go back inside to talk to my dad on the phone. (My parents have been separated for 3 years now.) I asked the officers if they thought a hospital would benefit me, and how long I'd be there if I went. They told me yes and a few of the benefits that would come with me going, along with how long I'd be there depending on my diagnostics. I agreed to go after a few minutes because I believed it would've been the right course of action, but my parents denied to let me go, and now I'm on probation and suicide watch 24/7 for something that wasn't my fault nor did I have any control over. I'm really struggling right now because I feel so crowded and it feels like I'm being punished for something that wasn't even my fault. Can somebody give me advice, or explain to me why I'm being treated this way?

(By the way, I'm no longer having ideations of committing su!c!de on my birthday.)
