Why is it that people react differently to traumatic experiences? I got PTSD after being raped, Does this make me weak?

Of course not! It 1st depends on how tramautic the experience was (though I'll make an assumption it was awful) and 2nd it depends on what happened and how strong your brain was

People can react differently to traumatic events while you end up getting post traumatic stress disorder after being raped because everyone was given a different challenge to be in and this is why how they end up becoming after it will be different than the other person.

No, this does not make you weak. If anything, it will make you cautious to people you may think are a threat to you. People to react differently, but there is no right or wrong way to react. It is normal to feel that way after such an experience, but in the end, you are stronger because you survived it and you can still live up to your potential today. Having this experience, you can heal from it and potentially help others who have gone through the same things. Many people do not know how to get through that kind of experience. When you get through it, you can be help to others

Absolutely not! Whatever happened during the rape, if you survived it then you did the right thing. All people are different in their reactions to events. Also, a lot of people deny their feelings after something like a rape and they act like it was not a big deal when in fact inwardly it was. Rape is very traumatic-it is an invasion of your body and it often ends up as PTSD. You can eventually get over it somewhat with therapy or maybe joining a group. It will take work over time to put it in a proper perspective. But you are definitely not weak!
