Are there any vocational services in your area or could your therapist/psychiatrist/case manager help you with perhaps funding a part time job (if full time is too difficult), even 5 hours a week would put you into a category of “employed” and you would maybe feel better. Is it possible?
Here in the US many people on disability work part time (unless disability is very severe), in fact most I know do.
If you work even a little bit you’d be able to afford more and maybe even meet new people. Is this an option?
