Hi,
Sorry to hear what you're going through. Firstly, I would try to focus on the positives. Its great that you are making strides towards a better future for yourself by getting on the degree apprenticeship. I would suggest using that as a basis to remember things will get better and to plan for what to do next. Think about what you vision is for where you want to be in 5 and 10 years time. That will help you recognise how temporary this hardship you're going through is in the big picture. That not to say its nothing or having no impact now.
I'm guessing you're not in a position to move out, but it might be something you want to try to make happen as soon as possible. Try to save up enough to get out. You can try to speak to your university, they might be able to support (you are technically their student) with housing accommodation if you are able to explain the situation, or point you towards further help and support.
Not a professional, but sounds like the medication probably won't work. The direct causes of the depression and anxiety are coming externally and continuously from your parents, its not past trauma that has stopped. Medication can only do so much, and help treat so much. You will need to find your own solutions that take you out of the "fire" and deal with the cause, like getting away, or setting boundaries before you can address the symptoms in this case. Try to get back to therapy if that was helping you, if you can.
I hope that helps and remember, you will get through this!.
