ugh people who suggest religion and that a seriously depressed person can just turn it off piss me off and I want to punch them in the face
OP, if you have serious depression, you need to see a doctor.
I'll say it again though: sitting inside in your house day in and day out is unhealthy and it can make it worse. Go out in the sun, eat healthy, work out, etc. It's not a cure, but it will help. Take breaks. Even if it has to be all day. Personally, I work out 5 days a week and walk my dog every couple of hours. If you sit indoors and stare at a screen with no human interaction, it's very unhealthy.
