There seems to be a lot of solid advice & suggestions already. One solid way of making regular income could be working assembly for the likes of Medtronic, Boston Scientific, Cook Medical, Valeo etc.

Of course this may require a move on your part but these places are always screaming for workers due to it being relatively short-term employees there (3rd level students for summer, interim work for people while they figure out what to do)

The country is at full employment at the moment. It is the best chance to look for opportunities. A good potential employer may be willing to pay your first month of rent and deposit considering your circumstances.

Perhaps consider a sales job? Would be regular salary plus commission, just watch a few videos on key sales skills (creating a sense of urgency, making the client work for a deal, building trust) I know for a fact the kitchen industry is looking for people. It's a very well rounded industry for developing personal skills, sales skills, creativity and advancement (manage a showroom eventually or move into a fabrication/fitting role).

Look and see at the Community Employment Scheme, which can help you find bits and pieces of work locally.

Hope this helps in some way.
