Stressed working from home

[Unsurewhattoput]

Is it possible to be signed off with low mood/stress when working from home?

Basiaclly I am in a job I hate (but won't quit bc of the covid situation) , I am also required to do online training with a university. Thsi week my daughter bubbles popped at nursery due to apositive covid case so she will be home for the next 10 days. Basically I just can't cope anymore, it was bareabke before Xmas because atleast I went into work and things were open so I had things to do. But with no end in sight everything is just really getting me down and I know it will be extra hard this week to work from home with my 3 year old, on top of this her sleep has been dreadful recently.

I was signed of work for a week in November but that was when I was in work, but now I work from home is it possible to get signed off work for a week, I literally just want to hibernate - I dont feel suicidal yet but I really just hate my life and nothing I am doing is to the best of my ability. I just dont know what to do.

I just feel at the end if my tether and I keep forgetting small but essential thing at work/uni, and im just not coping anymore

I am sure you could be signed off, you need to contact your GP. I hope you feel better today, it is shit when you think you are doing everything badly. The university would probably make allowances too, the important things are you and your daughter.

You self cert for the first week of sickness you don't need a GP note

Yes you could be. But, my two points would be that you're not really in any different position than majority of other home workers. Possibly better given you're not also expected to juggle homeschooling as well. So I'd review this as ultimately its one week of managing.
Secondly, you've had one bout of being signed off, now a second, you'll have most likely hit the threshold for when your emoloyer could discuss your absences and possibly be given a warning. Sickness warnings can lead to dismissal. Is it really worth that when presumably you could just juggle for 1 week?
Do you have a partner? Father of the child?

There is no point comparing yourself to other people, but I suppose it does depend on the nature of your employment. It is hard to juggle so many responsibilities, can you talk to someone non judgemental? Even ring the Samaritans or similar, you need support and space to think through priorities and how to cope, which is hard when you are stuck in your own head.

I have worked at home for years and yes I have been signed off sick. Sometimes you are too ill to work even if you work at home. I would though usually work through illness that I might not manage to commute into work. Self cert initially but I would talk to GP, also see if your work have any support schemes.
