too many restrictions?

i am currently 18, and have moved in with my grandmother,72, to get to know her more.
i go to college full time, and work two part-time jobs (somehow my life isnt very busy)

my grandmother is an interior designer and has her own business. she was also married at 16 (she had a tough home situation) and moved a lot due to the army. because of this she is very demanding and controlling. which in my view is completely understandable- i am young and able to change, while her life is set in stone.

my problem is, she wants me to not date or have friends that are male, in the service, married, older, younger- THE LIST GOES ON FOR AGES. pretty much, her friends -although funny, nice, and interesting- are my friends. she is constantly saying to me, "when are you going to make friends your age?"

i hate to say this, but im so bored with my at-home life that i sneak out at night -not to party, but to hangout with people my age. i have a feeling one day ill get caught, but what would be my punishment? not go out- i already do that!

how would you handle this situation?
