Should I talk to my boss?

So at my job we have year end ratings, I have a meeting with my boss in regards to mines. However there are some issues with work I’d like to express to her, my only issue is with doing that I’ll be throwing some ppl under the bus. And these ppl have a good personal relationship with her which makes me feel they will just go to them with what I say and then that person will go to their friends and whisper to each other and then I’m the enemy. I’m not wanting to call them out personally but we are supposed to be a team of 3 but in some incidents I get treated like I’m not apart of it. Ex. If it’s A and B and I’m C. A would say to B (while I’m present) “we have such and such to do”, or “I’m going to do this now”. Which makes me feel like they don’t want to work with me when it’s my job too please note I’m still learning in this area so I still need some guidance with certain things. I’ve always been the yea ok kind of person and never expressed myself or issues. But this has made me hate my job. I feel like expressing myself will just stir up the pot. Should I still express my concerns or just let it be and try to find a new job ?
