I know what you're saying! I'm in the same boat - have just done my course and have done 2 sets of acrylics on myself, 1 set of gels on my sis-in-law and a few manicures. My nails have been on for 2 weeks and am due infills. On my course we were told how to do it, but not shown (coz we applied the nails during the week so no infills were needed on anyone!).
I keep looking at mine and putting it off and thinking 'or should I just remove and do a new set?'. It's crazy! I'm gonna take a deep breath and (hopefully) do mine tomorrow. My sis-in-law comes back from hols tonight so will be interested to see how her gels have been and will probably remove her ou are accredited does not include rebalancing and maintenance!!s and do a new set coz I wasn't 110% happy with her final result!
Good luck with your infills. I'm sure we'll both be fine - the first time is always nerve wracking, we just have to take our time! x
