My goodness, you really need to do your homework. First I suggest you learn the different levels of employment within the medical field. You need to understand how much education is required for each position and what the responsibilities are for each position.
After you have this basic information, you need to get informed of the pros and cons of enlistment verses commissioning as an officer. Talk to former enlisted and get their take on officers and enlisted personnel.
Then you need to make an informed decision about what you want. INFORMED DECISION. After you have decided what you want, then go talk to the people who can help you make it happen. This is your life. Don't let anyone talk you in to something you don't want.
I will tell you this. If you don't pass your medic training, you are going to end up in a job you didn't want. You better study like you want this job. Many don't pass because they make poor decisions about how to manage their time in training.
It's time for you to get to work.
