Easy to do though mate, and if you're not educated (like so many people) then how are you to know any better? I ended up in a downward spiral in my 20s, thankfully I was able to get it shifted all onto a 0% card and clear it over a few years.
It's not bothering me at all tbh, it's managed and we still live very comfortably. Ultimately it's costing us buttons at the moment but when it's all done and dusted we'll be absolute ballers
