Do you find it impossible to trust people because of past experiences?

I have very literally been betrayed by one of my oldest friends, so yeah, to some degree I do. I'm almost always suspicious of people's motives and trust can be hard to truly earn from me. That doesn't mean I won't superficially trust in someone, at least, though. And I don't mean superficially as in the trust is fake, it is still trust, just that there is a hanging suspicion underneath it.

Kind of like a "I trust this person... [i]but do I really? 🤔" Which is usually followed by "Yeah, I guess so."
