I am someone who takes my friendships seriously because I don't have many close friends, but many acquaintances. But anyways, there's this friend I've known for a while, but to put it straight there are aspects of her personality that really annoy me, those little annoying habits, that have gotten quite bad recently (well I've come to notice them more). She has **** going on in her life and I completely understand that sometimes it can make you become really focused on yourself which I completely understand and sympathise with.

But should I tell her that some of the stuff she does annoys me (without coming across as someone who wants to change the person they are), among other various things, it's a very long and complicated story.

I realise 100 percent that relationships take a lot of work! and I really want to put in that work, she is a really close friend. But sometimes it doesn't feel reciprocated, as in, she doesn't seem to put in the same amount of work.
I know I have many many flaws but try to change myself if I am annoying someone ect...

Just need some down to earth advice !
