When I first went on Prozac for concurrent depression in college, I knew I had to eventually tell my parents. It ended up being bipolar disorder, but that's down the road. I basically just sat down and wrote a letter. I poured out how I felt in a letter and then sat my parents down and read it to them. That way I could take the time to edit what I was going to say and also make sure I included everything and anything I had on my mind. I also asked my doc if it was ok if my Dad or Mom came with me to one of my appointments so they could talk to him about my disorder/problem and ask any questions they had or if there was anything they could do to help me. That would be the big second step after pouring everything out.

Now I'm not saying it's easy. It's much easier said than done. However, I think that's the most organized and simplest way to start a conversation with your parents about your feelings about life. You can also include your friend if you feel that would help her understand what you are going through. I wish you all the best and I hope you get through this first step so that you can get the treatment you need. Good luck!
