I feel depressed about my life. Is this common?

Asked by lovelessness (659) September 9th, 2013 from iPhone

I am in my early twenties, and I feel sad about where I am. I’ve always been a dreamer, a girl who wants what is hardest to have and a perfectionalist in many ways.
I always think “it could’ve been better”, “it could’ve happened” etc. after whatever went on and I feel very sad.
It is not particularly about how I am and stuff, I am in a place where I am comfortable with my personality. But physical wise and situation-wise I just want to be in a perfect place.
I just have this mindset that if I am alive, and life has so much to offer and so much is going on, why cant I have all I desire?
I always have crushes on slightly famous artists I get to meet. This also makes me so depressed in the end.

I am a bit schizophrenic, but just a tiny bit. I was seeing a psyhiatrist and he told my parents that I was very smart.
Do you guys have this problem as well? Or is this a problem? Why am I like this? I can’t enjoy anything for a long time because it ends and I can’t fully get what I wanted.
one of the main reasons I want to be a somewhat known artist so I can have the power and comfort I think I need for my lifestyle.

Please don’t insult me, I am trying to be very honest here on Fluther, and I try to be blunt. I have received amazing answers to my embarrasing questions before, and that’s why I decided to ask this life problem away.

Thank you all…
