I try SO hard but I still fail?

I've just received my essay results worth 40% of a module.
55.

I'm honestly just...so gutted. I tried so hard to do my best; the feedback is awful, as my dazed supervisor keeps going on about how everything I did was "incorrect" and "wrong". I don't understand - she gave us a guidance sheet telling us what to do and I followed EVERY LITTLE THING SHE PUT ON THERE.

I'm pathetically crying right now, but not JUST because of these results (though it definitely heavily contributes). It's just that I'm in my 2nd year of uni, where this semester's worth 10% of my final degree classification, and seeing as how my first year of uni was so difficult due to the deaths of several close family members, I thought this year would be a fresh start.
I'm aiming to get into a really competitive PhD course, and so, alongside volunteering/part-time work, I set myself a goal of reaching a 1st for this semester. I truly, truly did try; I spent hours and hours in the uni library, researching all sorts of studies. I got my friend to look over it, and she thought it was brilliant.

And yet i still failed.
This is like, the third time I've failed this year. Meanwhile, several friends of mine who have partied every night so far have achieved higher marks.
Every time I've failed, I shook it off and tried to stay optimistic but now, I can't. I'm tired of trying all the time, and never being good enough. It's so humiliating; I've never told anyone - not even my mum/siblings - how much I'm struggling, both emotionally and academically.

I need some advice, because I feel so low right now.

The first thing you need to do is email the tutor that marked that piece of work right now and try to arrange a private meeting to discuss the work and work out exactly how things went so wrong in the first place. Until you understand why the work was marked the way it was, you will have no confidence in the correlation between hard work and good results, and will probably stop trying. Nip that in the bud now.

Re-examine your methodology, something must be wrong somewhere.

Ask your friends who got higher grades and observe how they did it. Also always beware of lecturere so called guidelines , many a time it's the unsaid things which are more important.

Should I email her now? I genuinely feel like I should re-appeal this work, as in I don't think it deserves a 55.
That said, I'm worried in case she'll think I'm wasting her time or something, and that I should just "get over it".

55% isn't a fail, isn't it a 2.2? Bit dramatic. Arrange meetings with tutors to see where you're going wrong.

I think you need some professional help; a personal tutor if you have one - or some counselling especially if you have suffered a bereavement (to say nothing of several bereavements) - or maybe you can find a final year or PhD student to help you?

Have you read the OP?
It's a fail if my efforts are much higher than that of a 2.2 . It's a fail if I tried to get better and improve optimistically form the past two fails I've received, and put in 110% only to receive a 55. So no, it's not dramatic.
Cheers though.

I have but it is dramatic to consider a 2.2 a fail tbh. You might not have answered the question properly, your argument might not have been very coherent, your writing style might need work. Your referencing might not be enough, I was recently told I couldn't get higher than 65 on a piece of work because my bibliography was too short. It could be any number of things but if you have tried your hardest it's not a fail. Your semester is worth 10%, that's really not very much at all and getting yourself worked up over a 2.2 isn't going to help. Your tutor's feedback doesn't sound very helpful to you BUT if they are saying things are wrong, at least you can see where you have gone wrong and can improve it?

But that's the thing - she's mentioned nothing about any limitations. She just gave me a mark, told me that my discussion was great, but "bits are choppy" and left it at that.

You're right though. It is only 10%. I guess I just really, really hoped to get something higher than my fails before, and seeing those marks just completely ruined my day.

My friends are all doing different topic areas marked by different supervisors each, so a direct comparison can't be made, and even then we all do it similarly in terms of how we present the information. I just don't understand.
