I am not sure if your employer is obliged to alter your shift plan, try talk t, maybe it's possible to do something. But if not, you can look for another job with a more suitable shift plan.
Hi,
First don't panic,
I think you should find out your diagnosis, and then start looking at what you can and can't do. You can find a lot of useful information on this forum.
Hi,
Have you seen a doctor? Maybe you should change your medications or your diet. Consultation of the doctor in my opinion is better than self-treatment.
