So reality is setting in after a couple years since my psychotic breakdown. I have a regular job that doesnt challenge me the chances of getting back into my old field are quite low arent they?
Don't be so sure. You might be surprised at the number of people who are able to successfully cope in their chosen fields of occupation.
Others may find it of more value that you are a dependable, competent worker who others wish to work with.
I can only suggest you try to not jump to a conclusion about your prospects in returning to your field of work as many people are able to manage their illnesses with surprising resilience and determination. Google famous people with mental illnesses. There are a wide range of professions and mental illnesses that have affected those that you many even admire.
Second chances may be worth taking.
Wishing you the best of luck.
