if you're genuinely frightened of someone you know seeing things you've said here, then you should probably stop posting, i guess. or, just stop saying shit online that could be traced back to you - nexters or not - that could get you into this perceived "trouble."
what you do/say at home is your own business anyway, so why would an employer have anything to say about it? and who cares if there's some awkward moment after someone reads your shit? there's no reason to feel awkward about anything, you're an adult, you're a good person, just laugh it off and continue living your life. who gives a shit?
