Just to add a few things to Buffy's answer:
What you are describing are some of the symptoms of clinical depression. There's no reason to panic, it's really common to go through a bit of depression at the end of the PhD (did it myself and know more than a few people who did). I would even claim that it's a quite natural reaction to the end of a long period of stress... and very often to the beginning of a new period of uncertainty.
That being said, it's really worth seeking professional help, if only to be reassured that it is indeed a temporary thing due to the professional context and not anything serious.
It's also normal to feel lost and confused regarding your career at this particular stage. Going through a PhD is a quite special experience which often affects us even as a person: we are not exactly the person we used to be at the beginning, and not only because a few years have passed! It can be confusing and it often takes some time to fully realize and digest these changes, including realizing the range of skills one acquires during this time. Very often people think that what they have learned is some very specialized knowledge about their field, but there is actually much more to it.
With some time and perspective you will feel better about yourself and discover which direction you want to take in your career. For now if you can afford to take a real break far from anything related to the PhD, preferably with some relatives or friends who have no relation whatsoever to this world, that would be the best way to start the healing process.
In my case I was applying for postdoc positions and got rejected every time. After about 6 months, when I had almost lost hope, I got a positive answer out of the blue. The following year of postdoc in a new town, new institution with new people and on a new topic turned out to be beneficial on every level. It helped restore my confidence and made me understand where I stand professionally and where I want to go.
I wish you the best.
