Struggling

Hi All, Just joined this group. I have struggled with anxiety & depression my whole life. I'm now 51 and find myself going down a hole to the degree that I'm struggling to do anything constructive. I really have little to be worried about but am walking around in a constant state of fear & dread. I can't think straight, which makes work even more dreadful. I'm trying to get up the nerve to maybe take some time off, but then the voices start in and try to tell me why that's a weak move and how I should just push through it. Intellectually I know this is bad advice, but part of the anxiety has to do with my sense of self and its voices scold me for being weak. Does that make sense? I just want to feel better.
