Purpose in Brief Thoughts

I know I bitch alot when I am here. I don’t mean to. When I was a teen, when depression began to truly take hold, I still had an overwhelming sense of purpose, as if there was something in my life I was meant to be here to do. That held through for years and years. Through college, marriage, and multiple returns to school. Problem is, now, I just feel like I am waiting for the end. That sense that I have a purpose to be here for is gone. It feels like I have already accomplished whatever I was meant to be here for.
