Enjoy your paranoid life. Imo the ideas you're writing indicate very high levels of stress, which can lead to unfounded mistrust of others and general misanthropy. If you could see it more broadly you might see that the people "taking advantage" are also suffering, and have more in common with you than you appreciate.

It's ok to be yourself around those people, to let down your proverbial guard, while having appropriate boundaries and not being exploited ... But over focus on who exploits and who is exploited blah blah blah ... All of that is quite toxic. It can make you just as miserable as the people you're accusing, if not more. And if you see every interaction this way, it's only a matter of time before you start seeing potential exploitation where it doesn't exist.
