I am a new grad with 4 months experience. I believe that with time, things do get better. I am less concerned with "fitting in" than doing my job because that will come in time. I was a tech also and know how hard I worked in that role. As a nurse, I help my techs as much as possible if I can. For example, I am learning how to cluster care for my patients. If someone who requires complete care and I need to give meds, start an IV, do a skin assessment or whatever, I tell my tech that I will give them a hand with bathing and dressing while I am getting some of my work done at the same time. I always show my gratitude with a "thanks for getting that done" or a compliment. As a result, things get done without me having to ask more times than not. There will always be gossip among techs. Some have been in their jobs for years and years and have seen nurses come and go. Don't let it get to you.
Now the IV thing, I always, always tell my patients that they will feel a big pinch so they know what to expect! Yesterday I started an IV and told my patient that she would feel a pinch and she allowed me to stick her 3 times! This is also a skill that gets better with time.
Hang in there!
