You're not the first and you certainly won't be the last. It's really hard to do anything with an Arts degree at the moment (anecdotally has been since the recession started). You did the same degree as me, by the way. It's useful for employment isn't it (sarcasm)? I almost went down the PGCE route but as much as I hated min-wage work I knew I would despise teaching. So at least you worked out that you don't enjoy it and it's an avenue you've explored.
Now that you know what you don't like you can start looking for what really inspires you. You have to forget about what other people think and just follow your heart (cliche but true). If you happen to be unemployed (not sure if you are) and no older than 24, you can take level 2/3 qualifications for free even with a degree (government pay for them). Best ones to do for career changes are vocational qualifications. If you're older than 24 though, employed or not, the best thing to do is simply be honest with yourself about what you REALLY want to do if failure was no option. Then research every possible means of getting into that line of work. Not everything requires you to get new qualifications - you could be entrepreneurial and start a business - it won't happen overnight but the sooner you start the sooner you can get your business up and running (you might eligible for grants too if this is a route you're interested in!).
I think what you will find initially though, if you completely leave teaching, is that with your degree and without teaching, it will be difficult to get into anything worthwhile (i.e. pays well, uses your brain, something you enjoy) quickly. In other words, you're going to have to put a lot of time/effort into whatever path you choose and there isn't likely to be a quick fix - so you really need to choose a path you really enjoy or you will soon be disheartened. There are lots of arts grads working in min wage work that does not utilize their skills at all - so at least with teaching you can earn enough to actually live and you can use your brain. So take some comfort in the fact that whilst you're working towards what you really want, your current situation could be a lot worse.
Personally, if you're looking for a 'permanent job' in anything other than teaching, with a Philosophy degree (and most other Arts degrees) you're going to be bitterly dissapointed. I'm a Philosophy graduate, 3 years since I graduated and I'm going back to uni to retrain because with a degree such as ours, the options are very very limited and unless you want to join the Army/RAF as an officer (it's not for everyone), find a mundane graduate job (like retail management, no thanks!) or work in an entry level office role then there's really not much else. NHS jobs are a possibility - but you're more likely to get into the admin ones (band 2 on **** pay) than care ones (also **** pay) unless you build up experience via voluntary work.
There is no point, IMHO, of just blindly searching for a 'permanent job' other than teaching because most of those jobs (if you can get one) will be much worse than teaching.
You need enjoyment, money and security. Most people don't get all three! A lot of people don't get any of those 3. So as much as you might dislike teaching, it could be much worse - most people don't skip to work.
Basically - figure out what you genuinely like and work from there. Once you have an idea of what you want then pursue all avenues that can get you there, just be careful of setting out to find something that will make you super happy - most people use their spare time for that. If it was all easy it wouldn't be called work. Unfortunately, most jobs become mundane after a certain point but they keep a roof over our heads and food in the fridge - it's just a means to an end. If the job front is dismal, maybe look into teaching abroad or finding other areas of teaching you could move into?
Best of luck!
