Moderate to severe depression is really a way fo professionals to rate your mood, so they can see progress or change. Your pain, however, is as bad as it feels to you. If you are the worst you have ever been or can imagine, then you are suffering and need taking seriously, which I hope they are doing for you. I really feel for you I have lived with 'mild' 'moderate' and 'severe' depression, and all require strength and determination to get through, whether you're able to work, drive or struggle to string a sentence together is pretty irrelevant when you're trying to survive. You are a valuable person and I'm so sorry life is so hard for you at the moment. Remember how you feel when you are less depressed and hold on to it as you can get there again. Life can be better so hang on in there. If you've been better before you can be better again. I hope you understand Me as I'm rambling , hugs,
