Working from home - no longer available!

Hello,

As an autistic adult I took a job about a year ago on the terms i could work from home the majority of the time due to the stress of commuting and the work environment. This is completely possible with my job.

I've now recieved an email saying that all employees will be required in 3 days a week from next month. This has of course stressed me out and has me worried both emotionally, physically and financially...

Is there anything I can do legally within reasonable adjustment? I cannot deal with the migraines, the small talk, the general hubhub. I can't work under these conditions to the best of my ability...

Thanks
