I don't feel...alive?

I know it sounds edgy but I don't know how to describe it better. I have my university entrance exams for med school coming up this year, which are notoriously difficult. My parents want me to succeed and also often told me that I can choose another career path if I want to which I refused. Now they want me to study but the way they sre trying to push me to study just feels a bit too "suffocating". I only have a set amount of time I can use my phone for after school which is fine I suppose. But everyday I get told to study and whenever I am at my phone I receive angry remarks which just make me feel like a failure. I don't know if slowly the stress has been accumulating or something but since yesterday i have just felt...off. Almost as if I am far away from my body. It hasn't even been long since I started studying. Even doing the simplest things feels a bit like a chore. I also don't seem to be able to calm down. I try to meditate occasionally but this is the first time where I couldn't empty my mind I think. I just feel so restless and kinda feel like I can't do anything.

Could someone please offer advice? Thanks in advance
