[quote=Kyuki]I'm going to be 110 percent honest with everyone here... I blame myself for the rape.[/quote]

Bullshit. 110% bullshit.

Halo already explained why far better than I can, but this is [u]not[/u] your fault.
These were the people who attacked you. They were the ones who committed the act. They were the ones cruel to you.
You blaming yourself is exactly what they want you to think, so you don't take action against them for something that is completely their fault.

[quote=Kyuki]I have been in constant contact with the police. Reporting things but they keep telling me they don't have much evidence to make an arrest. Unless I pressed charges for the rape. They have a written statement from the guy that did it admitting to it.[/quote]

Then press charges, otherwise they're getting away with it with no reason to stop what their doing. Because they aren't getting punished for their actions.

[quote=mdk]Without enough evidence to arrest, you may still be able to get a . The burden of proof is significantly lower,and it will protect you, legally and otherwise, from unwanted contact.[/quote]

This. But I need to be realistic, these aren't always 100% effective.
My sister once got one over an insane ex (tried to burn our house down once). 
It took some threat from the police force to finally get the guy to back off.

[quote=Beatrix]You can still purchase a handgun yourself and open carry so long as the gun is not loaded and no bullet is in the chamber.[/quote]

True, but without proper training Kyuki could just as easily be disarmed. And once disarmed the aggressor would figure out for themselves there's no bullets. 
In other words, if Kyuki get's a gun I would suggest proper training with it to avoid the aggressor taking it for themselves.
