yeah i wish they would leave me the fuck alone.
They won't. You mentioned you have loving parents so I'm assuming they aren't your reason to ctb. (If this is a bad assumption, I'd be very interested in hearing more.) But this also means your safety and wellbeing is critically important to them. As a result, they will do what it takes to stop you, including extreme steps calling the police and involuntary hospitalization.
I don't know your circumstances or your relationship with your parents, but when things calm down, could you have a conversation with them about what is causing you to want to ctb? (not about ctb itself.) I realize this won't change their minds, but it could be beneficial in a couple of ways. They may be able to get you real help and move you towards recovery. Or when you do ctb, hopefully they will not blame themselves and maybe you can have some positive quality time with them not focused on ctb.
Again, only you can decide if this might be helpful in your circumstances.
My son came to me a few years back and told me he wanted to ctb but was too afraid. While I was crushed emotionally, I knew he needed help. I let him tell me what works for him, and I do my best to support him. I've dropped a few therapy hints, but haven't forced him. He's still at risk, but we've had some very good time since, and understand how he's feeling. (I would still be completely devastated if he did.)
Hopefully, you can have some patience and "train" your parents. If so, you might find it helpful for all of you.
I hope that you can eventually find some peace in all of this.
I'm sure your parents are so confused, be careful you may get a visit from the police or mental health crisis soon
