Thank you for your post. I'm really glad you decided to share what's been happening with you! It sounds like you've been going through a lot so I'm impressed you managed to summarise it in some dot points! There is definitely a lot happening at the moment.
In your post, you talked a bit about feeling distracted, empty, distanced and unmotivated. How long has this sort of stuff been going on? You also mentioned how you are renting now, and it makes me wonder if these two are related? Even though it might sound like 'just a house', it's very much a solid ground and base, so when we don't have that it can be really unsettling. If not, that's okay too of course - but it can help to think a little bit about when this might have started.
It also might be helpful to have a chat with the counsellor? We could talk for days trying to unpack all the things in your list but a counsellor is really going to be able to offer that support as well as advice without the slow posting back and forth! Is that something you've considered? Generally most schools have one, or there is Headspace/EHeadspace and Kids Help Line (for phone support).
Hopefully this helps a little. I am glad that you're here and just want to help you link in with other support too.
