Feeling lost

Having come from a secretarial role that had some responsibility of managing disciplinary hearings and whilst studying for my L3 CIPD which I have now passed, I secured myself a HR coordinator role in the same organisation however I feel this role is offering me limited experience to HR as the majority of HR is outsourced externally and my sole responsibility in my HR role is managing sickness absence. I am worried I have made a mistake and that I won't have much to offer in the future if I apply for more senior HR roles as my HR exposure is very limited in my current HR role. I have started seeing a mentor which I hope will help as at the moment my current role is making me lose confidence. Has anybody else felt like this when they first started out in HR and if so how did you go about gaining more exposure?
