If you are depressed and you're not diligently and vigorously exercising 5 or 6 times a week (at least 30 minutes uninterrupted at an aerobic level of exertion), you are like a person with lung cancer who still smokes cigarettes.
Two hours would be great, but you don't have to start out buying the whole farm. Start with smaller increments of time and work up. It's not a temporary fix -- it is systemic, and it makes an immediate difference in both your day-to-day well being and your long term self-care.
Saying "I don't intend to get exercise, ever" when you're depressed is tantamount to saying "I have no intention of feeling better, ever."
It is rough love, but Rose is absolutely right -- if you're hoping something is just going to magically fall into your path and leave you feeling better, not taking steps (

) to feel better on purpose, you are generating irritation and powerlessness not just for yourself, but for the whole world. I don't think that's what you're up to in life. I think you would like to generate something more inspiring, right?
