I fear not managing time wisely.
This will come with time, and you will likely not get a really good grasp of this until you are actually hired on at your first job. Part of it comes with knowing the routine of the floor that you are working on, and part of it comes with getting knowing your own routine. When you master both of these things you'll be able to manage your time.
I fear being bad at some skills.
You're a student, it's expected. ASK QUESTIONS and expose yourself to new situations. If you're able to practice a skill, do it. Start IVs, place foleys, do assessments, and get feedback on those skills that you attempt. You're not going to be perfect the first time, and maybe not even the second. Given enough experience though you will get better. Also, don't think that this is going to stop when you get out of school. You will be expected to use new equipment and learn new skills... get used to it and have fun. Don't be intimidated by new knowledge, look at it as a new skill that you can bring to the table when it comes time for an evaluation or for you to move on to another job.
I fear being incompetent.
Hmmmm, I think this is the hardest thing to address. What I'll say is that those who GENERALLY fear being incompetent rarely are in my experience (just like the patient/family member who says they don't mean to be a bother rarely are). Refer back to the first two points that I made. Put the patient first, put yourself in their shoes and treat them accordingly. I think if you do this you really don't have to worry too much.
