Why am I so stressed/worried about work if I don't care about life?

[Mono]

I'm not suicidal, but I am passive about living. I'm at peace with that, it's been like that for a long time. I can still enjoy things, I have awesome friends and enjoy spending time with them or on my hobbies. But if it feels like I'm just doing time, why am I even stressed/worried about work?

I'm open about my autism, people at work know and I also have a jobcoach. Recently I got a new job (within the same company, so I kept my internal jobcoach). The people are nice, I especially like my team leader. But the co-worker that's supposed to show me the ropes is very vague to me. He's a very kind and funny guy, but also the "But things seem to be going fine?" kind of guy.
I have a lot of questions, but I feel hesitant to walk to his desk for every tiny little question (even if I want them answered). Questions I ask through Teams, he skips half of them. Through e-mail seems to work best. He doesn't feel "safe" to me, not the kind of person I'd be completely honest with like I usually do with the direct co-worker that also guides me. My previous one was really anal (I mean that in the best possible way), the only right way to do this is like this, I want you to do that like this, etc. I knew exactly when I was doing it 'right'.

The work is done on the computer. Basically it's backlog stuff that needs to be moved over from an older system/program to a new one. There's no manual for the work, I'm completely dependent on my co-worker - I can't express enough how much I hate having to rely on other people in my work, especially when I'm dreading vague answers. Supposedly ever case I move over is still 'open' and will eventually be checked by someone else.
Every time I ask a question and get an answer, I run into something new - the tiniest difference and once again I have zero feeling if I'm doing it right. I've tried to just do my best and think, If I'm not doing it right, they'll tell me. My co-worker told me this as well. But I don't like having zero feeling with what I'm doing. This to me feels like doing a school test where you studied like crazy, but questions are asked slightly different and I don't recognize that. The test results could be either way, I could have an A or an F.

I can't really put my finger on what I want to do about this. But I don't start work again until upcoming Monday (been off work for 2 weeks) and I'm already stressed out. I think I had a panic attack yesterday evening, I was in bed and couldn't sleep, heart was racing. I don't feel like working if it feels like I'm just winging it, I want to be able to feel and see that the work I'm doing is actually good. Right now i feels half-assed to me, the opposite of satisfying.

If I feel so little for life, why do I care about this? Why not just do the work and go back to my games when work time's up? I'm sort of 'protected' - if this job doesn't work out, they'll just look internally for something else for me to do. Thanks for reading. If nothing else, it at least feels good to vent this. I'm not sure if I'm looking for what to do about the above, or actually want to know why I'm so worried, maybe both.

It's not clear to me what you're asking for, if anything, and I don't do support/validation, but it's possible you're doing a task that I've seen many times.

So FWIW:

This sounds like a kind of activity that's fairly common in IT, mostly in "old to new" system migrations, but sometimes in "current to better" migrations.

In general, the things that are actually done are simple: grab a block of data, renormalize it, copy the result into a target system. So simple that it sounds like it would always be cheap to automate it.

But IRL, there are many cases where data in the source system doesn't always match 1-to-1 with the target system. The older the source system is, the more incompatible "special-cases" there will be in the source system.
(there's a simple reason for this, but it's not worth describing here - what's relevant is that a lot of people (both business and IT) are blind to it, and make stupid errors by under-estimating the difficulty of the task)

Generally you automate what can be automated, then assign a person to handle the "special cases".
The expectation (not always justified) is that the person who does the work is able to recognize incompatible cases "on the fly" and either manually adjust them, or build up low-level automation for repeating cases.

There's one small catch that employers often miss: if data migration can't be fully automated, there's a fair chance that some of the special cases require "domain knowledge" about the business processes that the systems (both old and new) support/automate.

In those cases the best person to do the "grunt work" is someone with a relatively rare skill-set: low-level professional IT skills and an understanding of the business processes. i.e. it's not really grunt work at all.

If this is what you're currently facing, I can (up to a point) contextualize it for you. But not fix it - if my scenario is correct, your employer has made a mistake that probably can't be resolved via an online forum.

BTW there are ways to organize/structure this kind of work, and at scale to automate it. But that requires mid-level professional IT experience. i.e. even more of the skill issue I described above
