“Why don’t you just let go of the past? It’s over.”
It’s not over for some, this isn’t “Oh, crap I broke my phone! Whatever i’ll just buy a new one” my past is part of who I am and don’t get that mixed up with “my past defines me” because it does not. That’s like telling a rape victim to “get over it”.
“Just because someone else did it to you, doesn’t mean I will too.”
Yes, we know that, but that doesn’t mean you won’t. It’s much deeper than that, I don’t think that everyone I cross paths with is going to betray me in some way, I’m just more cautious than most probably to the point where it may be perceived as paranoia. Once again this takes time and personal growth to get through.
