Geis, it sounds like you'd be perfect for the job and any firm can be lucky to have you!!
Can you do it from home or would you need to travel?

Your job right now is just to write the CV and apply, and if it's meant to be, you'll get the job. (That's what I told myself when I then got a very cool job.)

I've sometimes worried too if I'll be able to function at a job, well if you never try you'll never know??

You're lucky to have found a job that's interesting and your skill-set and experience fit and you would be good at!

If you like this job and are good at it and can buy good stuff to eat etc then your health might improve and you might actually function way better than you are now?
