Yes I can relate to this. It's kind-of the way I am much of the time. I don't know what causes it though. In my case, I presume it is a mixture of depression & anxiety. The depression makes it difficult to work up enthusiasm for much of anything. And the anxiety contributes that antsy feeling. It's sort-of a "push-me-pull-you" sort of experience. Especially first thing in the morning, after I get up, all I want to do is go back to bed & pull the covers up over my head. But, at the same time, I know I would be too antsy to stay there. So I just stay up & do what needs to be done.

Beyond that, the only thing I can think of to say is that, somehow, perhaps you have to find something you can commit yourself to. I'm an older person now. And I find that routine becomes increasingly important... & significant... in my day-to-day life. I pretty-much do the same things day-in & day-out. And one of the things I do is to reply to posts here on PC... a lot of them! And over time, it has become something of a passion for me. It didn't start out that way. But that's what it seems to have evolved into... to a large extent, I believe, through repetition. So, perhaps, if you can find something you're at least willing to do (you don't have to love it at first), & if you do it & keep doing it, maybe over time it can become a life-raft, so to speak that, you can use to "float" yourself beyond the anger, boredom & annoyance you currently feel. I don't know... it's just a thought. I wish you well...
