Should I take a break from my PGCE/SCITT course?

In 2 weeks, I will be coming to the end of my second placement on my primary PGCE/SCITT course and I have had a horrible experience that is making me reconsider whether I should stay the course (no pun intended) for final placement.
Just for some background context, I had a total of 5 years of teaching experience prior to beginning my PGCE course back in September 2024. 2 of those years were as a TA/cover supervisor across primary, middle and secondary schools throughout the UK, and before that I did 3 years of TEFL teaching in China working mostly with kindergarten aged children, the latter of which I absolutely loved and is the main reason I decided to come back to the UK and apply to do my PGCE so that I would have the security of being a properly qualified teacher. The reason I mention this is because I wanted to stipulate that I did not go into teacher training blind to the challenges I would face, nevertheless, I feel like I'm drowning at the moment and I'm not sure if I have the strength to keep going.
My initial placement actually went well, I ended up working in the same primary school that I attended when I was a child, and many of the staff who were still there remembered me, so it made the settling in period a lot easier. I had a really lovely Y2 class, some mild behaviour issues but nothing that I couldn't handle. Both my HCT (Host Class Teacher) and SBT (School Based Tutor) were great and supportive and I really felt like I had progressed towards the end of the placement. All in all, I couldn't have asked for a better start to my PGCE course from my initial placement, I felt like I was on cloud 9 by the end and that things were only going to get better from there.
However, since starting my second placement, I feel like everything has just gone from bad to worse from the beginning. I have struggled to adapt to the increase in workload, I have a challenging Y3 class behaviour wise and I am just emotionally, mentally and physically drained. I was supposed to start a 4 week 'block placement' before February half-term which involved whole-class teaching beginning with 50% and gradually increasing up to 80% so that I can step into the role of being a teacher in control of a classroom. With 2 weeks to go, I have had to postpone my block placement 3 times, because my SBT has deemed I am not ready to take on the responsibility. I actually feel sorry for her because she has bent over backwards to accommodate my situation, but my frustration of just not showing any progress is making me feel like I don't want to go back for the final 2 weeks anymore.
My ITT course leader has come out to see me on several occasions and drawn up a support plan for my final 2 weeks, however, she has said that even if I were to make it to the end of my current placement, she feels that I would not be fit to progress onto final placement, and that, "I would be very concerned for your wellbeing if I allowed you to move onto final placement given your current state". She has given me three options moving forward and I am going to spend the weekend weighing up the pros and cons for each one before making a decision.
Firstly, that I see my second placement through to the end and try to do more accommodated lessons, however, she is concerned that I will not be able to do sufficient whole-class teaching in the time I have left in order to meet the standard needed to pass. Secondly, I continue to stay on the course, but they would remove QTS from my final qualification meaning I would only graduate with a PGCE and not have to do final placement. I am considering this option because I have actually done very well on the academic/essay writing aspect of the program, plus I feel like if I'm going to see the course through, it's better the get something out of it and not let all my work up to this point go to waste, rather than drop out completely with nothing to show for it. Also, I do have my heart set on going back to teach English abroad again, and from what I've researched the PGCE is an internationally recognised qualification, it's mainly just the UK where QTS is required to legally teach in UK schools. However, I also recognise that this could come back to bite me as well if I do go abroad again in the future and decide to return to the UK at a later date, where I won't be able to get work teaching in UK schools.
Finally, my third options is that I "take a pause" by putting my PGCE on hold for an allocated amount of time (the maximum amount of time I can take away is a year) and come back to it with a clear my head and restart from my second placement rather than go all the way back to the beginning. I'm also considering this option, however, I am concerned about the financial implications of stepping away (I have a student/maintenance loan covering the course which is my only source of income at the moment). Plus, I am worried that too much time out might not look good if I decide to go back and do end up finishing it, because it will look like I essentially got cold feet and might not be seen as a viable candidate when it comes to applying for jobs.
So in conclusion, this is my current situation laid bare. I feel like I'm stuck between a rock and a hard place and don't really know where to turn. The only way I can describe how I'm feeling about whether I want to stay on the course and keep fighting to the end, is "I do want to keep going, but right now I don't" so I kind of feel like I'm in purgatory at the moment. If anyone else has been through this or can offer any help or advice on my situation I would very much appreciate it.
