Hi,
It feels like things are really stressful for you atm, I'm so sorry to hear about the housing situation. Are your school aware of it (just in case things escalate/get worse?)? As your situation could be something worth mentioning in the teacher's reference.
As for personal statements, I believe you still have to write a 4,000 character statement and that it's only next year that the personal statement format changes? I used to be a music PS reviewer on here. I tend to suggest a five-point structure for music(-related) PSes:
Paragraph 1: Short introduction. Introduce yourself and the reason(s) you are picking this subject/these subjects. It could be useful to mention what your principal instrument (voice counts as an instrument!) is somewhere in this paragraph - though if it fits better in another paragraph, then that's OK too!
Paragraph 2: Music performance-related experiences. These don't have to be amazing/extensive/mindblowing. Try and focus on positives, achievements, and things you are proud of - but also mention the skills these experiences have given you (time management, working with others, etc.).
Paragraph 3: More academic music achievements (e.g. your EPQ), or you may want to make this paragraph about the other subject you will be studying. Similar to paragraph 2, in that you should mention your transferable skills and highlight these, as well as the reading you've done, etc.
Paragraph 4: Non-music extra-curriculars/achievements/experiences. This can be DofE, learning/speaking other languages, volunteering, hobbies, etc. Again, transferrable skills are important! Try to see if you can show a different set of transferrable skills throughout your PS (i.e. don't have time management cropping up 4-5 times!).
Paragraph 5: Short conclusion, reminding them why YOU would be an excellent addition to their uni. You might want to mention modules or topics you look forward to studying at uni (ensuring these crossover at enough of your uni choices to be worth mentioning!)
Make sure you mention your first instrument, any additional instruments, keyboard skills (e.g. Grade 5 piano, if it's not your first instrument) and theory grades somewhere in your PS, for ease of reading!
Good luck
