Should my mom have the right to access my facebook messages and diary?

[Job]

sometimes, everyone needs to vent some frustrations or work through some emotions. it helps us to deal with things and to not go crazy on other people. everyone deserves a private place to do this. some people have trusted friends, others write things out, therapists, etc.

while you need to respect your mom, she needs to learn to respect you as well so that you can develop your own healthy sense of boundaries and self identity. you can't do this properly if you don't feel like you have a place to safely express yourself.

if writing some angry things about your mom helps you to get the feeling out without lashing out at your mom in person, then it's good. it's her own fault for reading your private thoughts.
