My mom read my facebook messeges?

[Sara]

my mom took my ipod touch and literally read everything. she went on my facebook, twitter.. etc. The conversations i usually have with my friends have some swearing and my mom does not approve of that. plus i have this super close friend whom i usually pour my heart out to. i dont have any secrets from her, and ive been complaining a bit recently to her about what goes on in my school. my mom is really strict and she really doesnt like me complaining to others. she never knew i had this many stuff she didnt know about me. So after that i got severely punished and she took my ipod for a month, then she told me i wasnt allowed on social networks and i must use it wisely. I really dont think she should be invading my privacy like that. i really trusted her, but on the other hand im scared she might search it again. its been 2 months since that happened and i always get the paranoid feeling to thinking she might search it again im just really scared someone tell me what to do
like i wouldnt be deleting my fb and twitter apps and stuff, but seriously im just scared and insecure and i have no one that could help me on this. Im on my own and it sucks
