Hi Christian, I’m not a professional in this field, though I went this and therapies enough to earn a PhD (in MY opinion only!).
I called it “feeling overwhelmed”. The answer to the causes is the million dollar question. For me, it’s a lifelong challenge to improve along these lines. However, you don’t have to wait till the end of your life for it to improve some.
One trick that Mel Robbins said, to get yourself out of bed to start doing something, is count backwards from 5 to 0. It’s like the countdown before takeoff, in the space program. The idea came to her from watching something like that, or whatever, but she later did some scientific research and she found something to back it up. Regardless! if you countdown from five and jump out of bed at Zero, you’ve broken the immobility’s hold on you—this one time.
I wasn’t cured after that, but I could get out of bed when I did that. The other thing you need to do is to have tasks so small, that you can complete them and feel successful. If you don’t know how to break the bigger task into smaller ones, then just set a timer. I’m going to work at this for five minutes. After five minutes you’ve been successful. There’s a book called the power of 10 and it’s just doing that for 10 minutes. Whatever you choose to do if it’s easily attainable, and in the success.
