<human>: Can you give me a shortened version of the text?

After just a few weeks into this semester, I suddenly found myself really depressed. I lost all motivation for pretty much everything in my day to day life, and the only thing that I didn't screw up was going to work. I stopped going to class, I seriously couldn't muster up the motivation to get out of bed. The worst part was that I just didn't care. I saw the days go by and I literally felt nothing inside about it. I have missed multiple assignments this semester in all of my classes, and I am really afraid that I have screwed things up too badly to repair them now. Taking a medical withdrawal from the semester seems like the best option for me at this point (but I'm also not sure of this). The major problem for me right now is that I have no idea how to tell my parents what has been going on with me. I have lied to them all semester and said that I am fine, life is good, school is going well, I just generally try to keep those conversations short and redirect them. I'm so scared to disappoint my parents, they pay my tuition and if I withdraw from the semester I have wasted their money. How do I finally talk to my parents and what do I say to them? I just really want to feel like myself again, but I feel like that won't happen until I take away the heap of stress that I brought upon myself by screwing myself over in school this semester.

The part about my depression that is the most confusing to me is that some days it involves uncontrollable crying where I feel the heaviness of everything, and other days I wake up and feel nothing.    It makes me feel crazy when one day I can't stop crying about something, and the next day I can't even conjure up an emotional response about the exact same subject matter, or I just somehow don't even allow myself to think about it and just go through the day on cruise control. Is this a normal way to feel when depressed? (I am hoping so because otherwise I am seriously going to feel like a crazy person). Sorry this got so long, I was just trying to get everything out there that I could think of.
<bot>: I am depressed and it has had a big effect on my school performance. I'm afraid to bring this up to my parents but I need to, I just don't know what to say.
