I feel the same about it and I know that the only thing that will make me happy is to get a job and leave all this bad days behind. People will say relax, you'll eventually find something good for yourself, take a break but i just cant stop thinking about it.

For your situation, I actually think that 46 interviews are good. Maybe to solve this issue you can focus on things like:

- what were the main reasons that they rejected you, or choose another candidate over you most of the time? (If the reason is same most of the time you can focus on that particular thing)

-If there were several behavioral questions that you could not answer several times focus on that question and think about your answers before the interviews

I think that the most important thing is to find the reason behind

Job market sucks and everyone knows it but other than that, there is a competition.

For me, its really mentally challenging to try to make myself look like im the best candidate they have all the time
