People who who have not experienced a form of depression rarely understand what it really is.

From my personal experience, what Rohag wrote is so very true - no matter what your age is.

As a teenager you might discover it is better to avoid discussing your depression at great length with your friends. Instead, continue to enjoy the time you spend with them - even if you are only pretending to be happy sometimes. I believe that there are times when pretending happiness can actually help us start feeling happy. Those times - even if sporadic - are good for us!

Continue to be friends with your friends, be thankful that your parents are working with you to get help and counseling. As ShakyDreams mentioned - you are very lucky to be getting help now. Depression was a shameful topic when I was a teen. I didn't get help until I was in my late-30's and will always feel as though I missed out on many years of life that could have been so much better.

I hope you keep posting and let us know how things are going for you. We care.
