Insomnia affecting work - desperate for help?

Hi! Hope you're all doing well.

Very recently my insomnia has been kicking off much more aggressively, and it's really affecting my performance at work. While they are fully aware of the condition and how it affects me, they can't be dealing with my poor performance, and they're considering dismissing me. I am getting more and more concerned about my finances, as I would be spending much more than I would be earning if they do dismiss me. I was wondering if there are any benefits available to me (currently don't claim any afaik)? I have looked at sites like this income calculator *mod edit- link removed* and my monthly expenditure, and I'm currently earning £1,300 a month after tax and NI according to that calculator. Most months after rent, services, food, necessities and some saving I'm left with about £150-300. Would I be able to live if I claimed whatever benefits might be available to me, if need be?

Hope to hear from someone soon, even consolation would help a lot right now

Hi sumbes
I am sort of in the same position as you, I don’t think it’s insomnia but sleep deprivation.
Started Jan 2nd, I work in a school so finish at 2pm and I looked after my partners grandfather
who is housebound. I loved this man like he was my own grandfather and 30th of Dec last year
( my birthday actually) phone call from police, there’s been a fire, get round. He had dropped a cigarette at his feet and he basically burnt to death. Burns unit on life support and 3 days of no
Water or usual medication, just heavy sedation, and then he died. I haven’t slept properly since this
Went back to work, no support, to the point I was slurring my words sounding incoherent and rapidly
going down hill. I’ve been suspended as statements are implying I was out of it, was I drinking! Been off 6 weeks now,
Have you ever suffered any of those symptoms before because I may lose my job due to this. I never knew not sleeping properly could cause such problems, I knew I was very tired but not to the extent
I sounded out of it or incoherent?? Doc says I have traumatic grief response.
As far as I know, housing benefit will pay your rent if you rent and council tax. Job seekers is £72 a
week. You need to find out if your insomnia can be classed as a disability? and then you will receive more money to live on. Like you I am terrified I will lose my job, but am hoping they will see it was a reaction to such a traumatic way to die and the injuries were horrific for anyone to see. I have nighmares about it when I do get a bit of sleep and flashbacks to the day and days in the hospital. I am a mess who has been put on antidepressants and may be jobless.
I know how you feel, how can you try to get back to a manable sleep pattern
when being dismissed is hanging over you, this will surely make it worse. I assume they have noticed
but what have they said to you ?
How have other people on here managed work, and is it normal to not function properly through sleep
deprivation ?
