Welcome to Fluther. In all seriousness, and since you already know that you suffer from depression – for which I hope you are receiving some medical treatment; are you? – I would suggest that you discuss these feelings in just this much detail with your physician. You may need to have your meds adjusted or changed. Because most of this sounds like “classic” depression. With social anxiety on top of that, and the other effects from depression such as excessive sleeping, no exercise, lack of sunshine, etc., you could spin down into an even worse place. And I hope that you won’t. Talk to your doctor. Life should not be so miserable.
