I'm not going to share my feelings to protect myself.
Why would you do that?
It's a matter of life and death.
It sounds like you're dealing with a serious situation. You know the details of the situation better than me, obviously, but there are times when it's perfectly acceptable to hold back a bit. You should prioritize yourself.
It's wrong to force other people to share their feelings.
If you really feel that you can't do this then you don't have to. No one should force you to share anything you don't want to unless it could save your life.
