Very worried I've just thrown away the last 5 years of my life

So I made a thread (
https://www.thestudentroom.co.uk/showthread.php?p=76565810&highlight=) about two months ago about my job prospects as a recent MA student with zero relevent experience. I've lost count of how many jobs I've applied to but its definately over 100 now, maybe nearing 150. Given I have no experience, nearly every single one has been for entry-level jobs, internships or specifically for graduates. I specifically look for jobs under 20k as I dont expect to get any above it and I've tried local, national and global. So far I've gotten 0 interviews, and around 20% of people have actually replied/acknowledged my existence. I've spent hours upon hours with my applications - researching companies and what they do and how the role is suited to me and how passionate I am about their objective. Some even demanded writing tasks and sample blog posts which I would spend days/weeks researching, writing and editing, and after all that - yet some didnt even give me an email back saying I've been unsuccessful.

People said in my last thread to 'improve my CV' - with what exactly? I've tried to improve it for months but there is only so much I can put on my CV apart from my education and the fact that I've been working in a food bar since I was 16 - not that anyone would be impressed. Now I did say I have no relevent experience, people mentioned to volunteer instead. I can't volunteer in most some places because I live in a remote place up north and would only travel if I got a paid position as an intern, since I'm more or less broke with a *****y wage. Nevertheless in fact, I have looked into nearby places and applied for volunteering positions whether at schools as TA or with charity organizations - even at the cost of commuting 30-50+ miles and making my broke self, even more broke. But still nothing.

I know I'm not the only one in this position, but I definately feel like I'm in the minority, even the minority within the minority. I think almost everyone I knew at undergrad and postgrad have some graduate level job, or doing an internship, enrolled on a grad program - or done something! It's quite embarrassing also, I'm getting messages on facebook by old timers and my reply is I'm sill doing what I was doing at 16 and giving the same excuses again and again for why I can't get a good job. People will tell me to do something about it, but I feel I've done all I can.... I mean what else is there left to do? I'm not bothered about getting a specific job or my dream job in a certain sector, I'm just after a degree-level job so that my past 5 years hasnt gone to waste. I got high 2.1 and high merits at both undergrad and postgrad at well ranked Universities (Sheffield and Durham) so I dont see academic qualifications as a barrier. Experience obviously is, but I've tried and begged for it and still didnt get any oppurtunities. My regret is not getting enough work experience and volunteering at undergrad while I was at uni, but I never expected it to come back to haunt me this way. What else is there left for me to do at this stage? I just feel like I'm wasting my time... and potential employers who read my application and put it straight in the bin.
