I downloaded the Freecash app at the weekend - you basically play online games and get paid for it. I’m up to just over £25 (I work full time so that’s from a couple of hours in the evenings only). So it’s not going to be the solution to everything, but every little helps. Although you said something about no space on your phone - if I were you I’d delete apps I’m not currently using and install the apps for earning the money (maybe look at any videos you have on your phone and save them somewhere else so you can delete from your phone, same with any downloaded movies/songs etc).
I used to do something called Shop and Scan - you basically get paid for scanning all of your shopping!
Mystery Shopping can be good too - Retail Eyes was one of the two firms I used to work for. Another one I did was by Kantar I think.
If ID is holding you back, why not get yourself a provisional driving license? You said you don’t drive, so if you could learn to drive this could open up further opportunities to you. Are you claiming any benefits you are entitled to whilst looking for work?
I would say be careful not to spend so much time doing all these different things online to earn money that you aren’t focussing on applying for work!
Get yourself registered with temp agencies for anything you think you could do - care work, basic admin, basic finance roles, etc.
Set up your LinkedIn profile with your experience, ask friends and former colleagues to endorse your skills on there, and set your profile as actively looking for work.
Ultimately, if there were an easy way to earn loads of money online, we’d all be doing it already. Be wary of scams as people will try to entice you into easy cash jobs if they suspect you are desperate.
