I kinda want to take both sides.
I've suffered from OCD and generalized anxiety since I was in high school but wasn't diagnosed with it until my 20s. My parents ignored it, which resulted in a breakdown in my first year of college. I didn't finish college and really wish there was someone there to push me... I'd be in a much better place today if I had finished.
At the same time, I agree that your parents need to be more understanding that depression makes it hard to have the motivation to do anything. They need to understand that you have good days and bad days, and try to be there for you when you're having a bad day...
