What can you do if you live in germany (or in one of the germanic countries) that dont protect you from stalking, death threats etc?

So the police in germany and other germanic countries like austria dont really do anything when it comes to stalking, death treaths until your stalker get physically abusive. Like wtf. Should the victims wait till they get killed according to the some police? We do have stalking laws but these are like joke , these dont even protect anyone. I am seriously scared right now. I did not know that we have such serious problem. I really want to know how to protect myself. If you live in germany/austria, how do you protect yourself from such problems?

I dont understand why some people think it is difficult to prove the stalking. If you get death threats thousand of times in thousand of ways via text messages or call for example, then you can show this to police. If you also get followed by the stalker everywhere everyday, civil police can check/controll it secretly if you tell the true. There are thousand of ways to figure it out, if someone get stalked. I think just some police forces are just lazy. We have stalking laws for a reason
