I decided to change myself?

But it feels like I am losing myself in the process. I want to change, but when I try to, I start to think what is it that I need to change that I can't see. Feels like I am changing myself more for the fact for someone I love who doesn't love me. I don't know at times why I do need to change. I have been depressed, high anxiety, and stressed out a lot, but that seems to slim down a bit now. Now, feels like all the things about me I want to change are actually good qualities and I am trying to wonder why can't the person you love a lot see that in you. I've made mistakes, super imperfect, not a suave guy, am confused more than actually knowing what to do. I don't know what to do. What is your advice?
