DS needs currently a lot of help due to MH crisis. I manage work with WFH and going to the office some days (my work can in theory be done fully remote). His MH declined and he is now suicidal and I have to provide 24/7 suicide watch. DS is allowed back some hours into school but that is part time only and I need to take him to reception and collect from there to ensure seamless supervision (secondary school). I am not coping at all with any of it. No idea long this will go on for. could be over in a few weeks, My stress levels are through the roof, I don't sleep, I cannot eat, I cannot focus.
I really dont feel able I can work. Would it be unreasonable to get signed off (been at my workplace for many years and haven't had a sick day in years) or should I ask for unpaid leave given I am not ill (though I cannot really afford it - hence the idea of going off sick,). My friend said I should do the decent thing and resign if I cannot effectively work and dont know when things will improve.
I am not thinking clear and I am one of those who never take time off and always soldier on. So could do with some advice.
