It's not always easy communicating with parents. I am guessing that by extending your studies you are meaning doing something like honours or masters or a kind of hybrid degree or similar? If it's something you feel really passionate about, I wonder if there's a way you can explain to your mum why it is important for you?
With your current psychologist, even after 10 sessions on a mental health care plan you can get another 5 on an Enhanced Primary Care plan that you do with your GP. You don't get as much back, but it's something. It depends how much you feel you are getting benefit from psychology sessions at the moment. And the uni will most likely have free counselling sessions too. At my uni it was 6 free sessions per year.
It can be hard feeling lost, when we have had a sense of what we want to do but other things seem to be taking us from the path we were oriented towards. Sometimes journaling or writing down a vision of what you want can be helpful, even including pictures of what you aspire to or dream of doing. That may help you restore a sense of direction and structure going forward.
And then, amongst all that, self-care is important too. So having the extra time from underloading may be what you need to take some time out to just be in the present moment and do some things you enjoy. Sometimes it is when we take that time for ourselves, just being present in this moment, that other stuff starts to sort it self out at a subconscious level. Just doing things we love can sometimes be grounding and bring ourselves back to what our core needs and interests are.
Is there anyone else you can chat to in your life about your feelings? Just staying in contact with people and talking things through can be helpful.
Take care.
