You can move in that direction, Eleny. You already have good insight. It can be slow-going to change something that is fundamental in our natures, but it absolutely can be done. Be willing to put up with some psychic discomfort, and be willing to experiment, despite the likelihood that not every experiment will go nicely for you. You are allowed to make some mistakes.

People will actually like you better when you evolve in the direction of being more authentic. It is not authentic to act intensely interested and hang on to every word coming out of the mouths of people who are droning on and on in a self-centered way. I still do that a lot, myself, and have to work on it. Lately, I am noticing that I am infantilizing adults when I am overly solicitous in my manner toward them and patiently listening, as if they were children who would be crushed, if I cut them short. Adults can deal with discovering that there is a limit to my interest in having them drone on at me. Actually, even little kids deal with that all the time.

I've worked in healthcare where caretaking was my role, which reinforced my tendency to make mysef totally "available" to those I interact with. I need to set limits more than I do. Otherwise, I don't manage my time well.

I strongly endorse the suggestion above that you get some books on things like "boundaries."
