How to deal with difficult family members when communication is tough and when it's something you can't really change...

[Unsure-But-Sure-All-At-Once]

Sometimes I find it hard to deal with certain family members--and although we are an open family, communicating is a bit hard for me, especially regarding feelings. I know communication is the best way to handle situations like these (letting the other person know how I'm feeling and how I see their actions) but is that the only way? I'm an independent person who likes figuring things out on my own....so I'm looking for resources regarding how to deal with these difficult emotions, because a lot of the stuff I find hard to deal with is personality based and the other person can't change it, if that makes sense. I feel like if I find some way to deal with these feelings, it will be better, because the things I'm annoyed about are things that won't change, that I can't change, and if I communicate what I'm feeling, it may be better for a few weeks, but then it will feel fake and forced and then it will revert back to the way it was before. I hope that makes sense--this was a bit all over the place and there isn't much context. I'm just looking for ways to deal with feelings of anger, resentment, and annoyance right now, as well as finding ways toward acceptance.
