I think that last one is pretty damaging the way you wrote it. I would slightly change this to say "Be honest about it with the people around you, if your friends or partner evidently look at you unfavourably, then consider whether they're on your side or if it would be worth trying to keep them around, a direct serious conversation can sometimes do wonders for your relationships, and socially isolating yourself can sometimes be useful but oftentimes costly. (or something to this effect, leaning on tangibly being unsupported by your personal relationships rather than vague notions of anticipated rejection)
Merely anticipating people might not look at you favourably is kind of a separate issue.
