yeah i think hiding might be a safety / defence mechanism...
if you don't tell others you aren't feeling so good then you don't risk them minimising / invalidating your feelings.

sometimes it can be hard oh so hard to express our feelings when we are used to hiding and when we feel bad like we are burdening others with those feelings...

and so when we get up the courage to express them they aren't communicated as clearly as they would be if we were more assertive with expressing ourself. but it can be hard to be assertive with expressing our feelings sometimes when they have been invalidated in the past... but it means that other people don't really hear the distress we are feeling.

or sometimes... people don't know what to say... or how to help... so they kind of avoid negative feelings and ignore people expressing distress because they don't know what to do.

do you have a t to talk to about this?
