You’re definitely not alone in feeling this way! Recent studies have shown that the average person will change careers 5-7 times during their lifetime and nearly 6/10 middle-income workers are currently considering changing their careers (novoresume).
You’re not stuck to a single career path and there will be other opportunities out there to find a job that you find fulfilling. For now, it sounds like to have the following options:
1) Complete your apprenticeship and continue your current career path
2) Complete your apprenticeship and change your career path in the near future
3) Discontinue your apprenticeship and change your career path now
Without talking to you and knowing your exact circumstances, from your post alone, it sounds like you’ve given your apprenticeship a go, you’ve learned about yourself in the process (i.e. what type of job you like / don’t like), and you can take these learnings forward into whatever option you decide to pursue.
It may help to build a list of criteria of what you need from your job to feel fulfilled i.e. write down the learnings from your current apprenticeship and really think about what aspects of the role you’ve enjoyed, what aspects you haven’t enjoyed, and what are the core values you need to have fulfilled in order to find satisfaction in your role.
Once you know what type of role you'll find fulfilling, you'll need to think about making a plan. Weigh up the pros and cons of discontinuing your apprenticeship, versus completing your apprenticeship prior to making any career change.
Hope this helps.
