I'm broken and I need a jump-start

Hi. So... I guess I'm sorta depressed. Is that what this is? I still function decently and it's not like I'm sad, but I feel like I've become sorta colorless, joyless, passionless. At this point I feel like I'm mostly just trying to survive day by day. I don't feel very excited and passionate about life and the future as I once did. I think college killed me. I don't know what happened. I guess at some point I stopped putting in the effort to take care of myself and now I'm here, dealing with the consequences. I'm sorta trying to get back to where I want to be, but it's just hard. I would ask people to help me, but I don't know how they can help me. Honestly it's all about my own actions and attitude. I don't know why I keep wallowing in this mood that I'm in when I know and keep telling myself that I just need to turn to Jesus, open up the Bible, and let the words renew my soul. Oh Jesus, please help me. This is not where I want to be. I never wanted to be at a point where I'm struggling to find joy and passion in everything. That's what I call turning into a grown-up. I made a promise to myself and to the world that I would never grow up, meaning I would never let the world of school and work and adult responsibilities take over my life in a negative way. I've destroyed myself. That definitely isn't to say that this can't be fixed... I know everything will be okay, but I would like to change this mindset soon, someway, somehow. I can't-- I shouldn't-- live like this. No one ever should.
