The worst symptom of my anxiety is that I find it impossible to sleep when sharing a bed, or even a bedroom. It's like my brain won't switch off with someone else there. It has an impact on relationships, obviously, but also on just things like going on holiday with friends because it's way more expensive to have to book my own hotel room rather than share. 

Does anyone have the same issue? Has anyone found ways to fix it? I'd be ok with not sleeping as well as normal, but it's literally like the difference between 7hrs alone, and 0-3hrs with company. I can't function if I share for days in a row.
