Hello Polarity: I see this is your first post here on PC. So... welcome to Psych Central.

Thank you for sharing your concern. We here on PC cannot offer mental health diagnoses. Plus I'm not a mental health professional. So I can't suggest anything with regard to what may be going on with you. For this you would need to see a mental health professional. (It may also be worthwhile to have yourself checked out medically just to make sure there's nothing going on that way.) Based on what you wrote, though, it does sound as though anxiety may be at least part of what you're struggling with. So here's a link to the anxiety forum, here on PC, just in case you haven't already found it:

The Depression forum may also be one to check out:

And then here are links to 5 articles, from Psych Central's archives, on the subject of anxiety plus links to 2 on depression:
