@Imperial - sorry to hear you're not having much success. Yeh I'd believe you when you say that even from work places that claim they don't discriminate do. I know from my past experience on selection panels for recruiting that the questions are asked about amount of leave taken and if there is any mention of a medical issue there is discussion about whether or not they can even handle the job. That shouldn't happen I know, but it does. For example I recall we had about 3 people tell us they couldn't sit down due to back issues so we took preference for people who could sit down. But then of course it would depend on the role you're applying for. Some roles they can't afford to put anyone in them that may be considered high risk for either fault or accidents.
I'm living with multiple conditions so I know my chances of finding other work will be very hard as I can't even do a job interview these days as I struggle with my talking and I burp a lot. I know it shouldn't happen, but I am fully aware that I'd be discriminated against even though I shouldn't be. It happens in my own life anyhow... I get the stares, laughs, and comments... nothing I can do to stop that.
Perhaps it may be a good idea to seek help from an employment agency or something like that? They may have some helpful advice or ideas on employers to try. I'm not sure what resources you have available where you are.
I wish you the best.
