I was going to suggest Timpson's and fruit-picking.
You could start with voluntary work and get yourself a steady record. This would help immeasurably. I'm glad that you are trying to see forwards. If you find any opening at all - go for it. Maybe no-one gives you an opening..... make one.
Mr. J2 was 62 when he was widowed. He and his late wife had just moved to France. She was a bit older than him and had her pensions so they reckoned that they could sell-up in UK, restore something to live in and survive. Reason they did that - he'd been made redundant aged 60. Jobs? No chance, no chance at all.
So there he was, on his own in France, no money coming in, no chance of a job and mourning a dearly loved wife.
Not everyone has it hard in just the way you have, Nailedit, but that was pretty hard, I think you'll agree. No real savings to speak of. French property values are low and he managed to sell and move to Wales (values also low) where, because he had no ties, he did antisocial-hours rescue-truck driving, until his pension kicked in. Even so, found it hard to manage and moved to France where he survived by restoring houses whilst living in them and selling them on. Then we met and joined forces.
Things CAN change. MrJ2 didn't think he had a chance.
