Worrying about driving?

So I’m 18 live in Australia and haven’t gotten my Provisional licence yet I’m still on my L’s ... I’m taking lessons doing the log book though have yet to do another lessons it’s been maybe since December or January that I’ve done my last and it’s like a mini test to see if I can do what I’ve learnt so far I haven’t really driven much since then and feel I need to practice a lot before I dare to book another... I am now on holidays snd it’s nearly dinishing and I feel embarrassed that I haven’t done it nor gotten them and I’m 18... I also feel scared and worry all the time about what the instructor is gonna think of me and feel a lot of pressure because I haven’t done anything ... I find myself thinking often about it and worrying and it’s becoming overwhelming daily ... to the point where I get anxiety over it ... help?
