was i molested..

last night at 10:34 pm i was hanging with my friends, something bad happened. i have a lot of guy friends and i fell asleep around them, i woke up with a pain on my arm and i was sun burnt but the pain felt like something grabbed me really realllly hard and come to find out i was touched as i was sleeping and kissed and basically sexually harassed but i didn't know it, i told my boyfriend and he's beyond pissed at those dudes and he feels really bad for me.. thing was my best friend was there and didn't stop it, i heard it from her boyfriend and i honestly don't know what to say or do anymore. i hate myself and i didn't even do anything wrong
