I absolutely hate my PhD and I don’t understand the purpose of it
Now I am depressed, lost, and hardly do anything. I wake up go to the lab and pass time. I absolutely hate my “thesis”


This is the problem; you are stuck in a vicious cycle. You need to meet with your advisor and come up with a solid plan - including a timeline - for what will happen in the next year or two. 

Given that it has already been 5 years, I suspect this plan should involve you finishing your current work, writing a dissertation, and graduating. But, you and your supervisor could also choose a different direction (i.e., starting a new topic or choosing a new advisor).


  I don’t have anything meaningful or useful for my future career. I don’t even know the purpose of my thesis topic. 


At this point it's probably time to decide what your career goals are and make sure your plans are aligned with reaching those goals. 


This could mean spending 1/3 to 1/2 of your time learning skills that will be useful for an industry career, and spending the rest of your time preparing for graduation. Given your level of burn-out, I suspect this is the wiser course, but I'm just guessing. 
Or, it could mean switching topics / advisors / institutions so that you will be competitive for academic positions in topics that interest you more.
