"Giving research a try"

--> That does not work in reality. You need to make a clear decision and you need to have the drive and committment or you will neither get an MPhil nor a PhD.

Well, it seems like you've made up your mind about this and decided to take this step. Therefore I don't think you need to worry about the consequences: of course every action cause a reaction but in your case you have the chance to make a new beginning with a new supervisor. After all, people may try to make life hell and your reputation within the department may suffer for a certain period of time. Nevertheless it is up to you to make an impact in your new relationship with your new supervisor - in other words, if you manager to impress your new supervisor through hard work and committment, the bad reputation may only continue through gossip of a few lost souls who see no other purpose in life than gossiping all the time. They are not important anyway and remember: all you want to do is to complete a PhD, so as long as you manage to do that it is up to you to leave your departement which might shed a bit of hope on your current situation. Respect for your decision, though!

calm down.

She can't expect you to be available on such short notice. Just send her an email and ask to shift the meeting to next week.

A PhD student is not a personal slave

In order to provide you with more details:

it didn't smell luckily, however, the noise could probably be heard in the office next door and in the corridor..

Once I've been sitting in a supervision meeting. Just me and my supervisor. It was very quiet as he was reading some paper I brought in. I've been sitting there and then: I farted really loud. I don't know why.

He pretended that nothing had happened but I thought I want to disappear forever...

Stay where you are-that's my only advice.

..I'm getting increasingly depressed.

My girlfriend (no PhD student) is drifting away from me. Or I'm drifting away from her. I hate it but there is nothing I can do currently as I feel very tired.

took me 20 seconds:

If you already fail at the hurdle of how to navigate a university website...then I think you should seriously consider a different career pathway than doing a PhD.

that's an irrelevant question, verdy, as it only reflects PAST achievements whereas sugar_student pretends to be a future star.

However, with your 14 hours per day you will sadly end in

a) the mental clinic (within 12 months)

or

b) the coffin

I think it's ridiculous that you even try to show off with such a number-you are definitely not an example for a good PhD student, rather for an obsessed/crazy one (with all due respect)

that would be a conceptual analysis in itself with the conceptual care system itself being the actual case study (rather than individual cases)

It's one common mistake to assume that "case study" is always a specific case. You have a lot of freedom to define your unit(s) of analysis and it can definitely be a system of care.

For example: you could compare one system with the German system through a case study approach.
That would be a multiple-case study with two systems.

Alternatively you could use a single-case study: the overarching unit of analysis would be the investigation of care systems, embedded units of analysis would be the English system and the German system which you can then compare within a single-case design.

Once again-read Yin..

You don't have to necessarily use grounded theory methodology to compare your data. We are talking here about the research strategy and all I'm saying is: in the case study approach commonly used in medical studies, a comparative data analysis is nothing special.

Various measures apply in this case to increase reliability and significance and certain sub-sets of validity.

First you need to be very clear about your research strategy regardless of both methodology and research methods chosen.

You can create reliability through case study protocol (s), chain of evidence, review processes and so on. Read Yin (2003)

Multiple case studies with comparative analysis-pretty much standard in clinical studies..
