i've no idea what you've applied for or what your field of work or applied for is, but i'm betting competition is pretty intense for anyone looking for a job/employment or a career too fufill aspirations or financial needs tight as things are with bills and living, I think it's great you feel capable enough too want too work, but dont beat yourself up because it's in no way your fault, also help needed from the Gov in the independent living fund enabling a potential employer too keep and retain your skills is under threat.
I would say i'd have a pretty impressive CV too from working in agriculture,horticulture,forestry, ministry of defence, firearms orientated environment too finally catering for 14 yr's, but i reached the end of the road not knowing at the time the cause.
If i did i'd have too be pretty honest in saying if i could go back into that things would be pretty tight in lots of ways, risk assessment in different way,adaptation, and in all honesty could i make a living for myself and be beneficial,useful, too a employer, at the moment i cant see that. that wouldn't be fair too me or them.
I also did agency work for a while, I don't know if you've already considered it,or looked at it or done it??, they should be disabled charter marked(that is who we are essentially even if we dont like too think in that way), but it used too be in a better climate a way too get a inside view without being a commitment of a full time employee, could open doors too moving full time if you like it and so wish, and gives you a taster for you of different work places too fit you and them.
All the best.
