Because you have it in your head that people will 'know' or be 'looking at you' with particular thoughts in their head,you have created a mind set that is set up to harass you.
Odds are that no one outside your manager knows,and if they do,they probably feel for you.Whatever is going through their minds regarding your private life,isn't of concern to you,unless they are loved ones,or friends who are supportive of you.
If anyone inquires,gently communicate that you are "fine,the issue is remedied,and a thank you for your concern."
Gahh I understand the wanting to shut down.I am experiencing some things from husband with whom I will be initiating a divorce.Things are ugly,(not as bad as w/ you atm,but,it feels ominous to me).
One step,breath,issue,moment at a time.That is your concern.Just the moment you stand in.Don't worry about 5 min. from now,or yesterday.You only have power over this moment,and the strength is w/in you to effect the moment with being mindful of what's going on in your head,and,to find what positivity is there to grasp at.(Easy to say isn't it?)
