How do you stop giving up on yourself?

My birthday is just in a few days and I am not even looking forward to it and I feel like I have lost my true self since age 22 and now I will be like 28. I just feel like so stuck and lost at the same time. Not sure what to do and to do. I just seem to lack that guidance or path on what to do. I told myself so many years ago that I want to go to college and get a degree so that my future will be secured. Then I said I will conquer my fears of driving. And I even said I will put myself out there because I have always been this quiet, shy type of person. But I always seem to give up before trying anything and my inner dialogue is so negative which I just don't understand. I just don't feel proud of myself and I seem to be wasting my potential now. I don't even know if I have that in the first place but I'm sure everyone does. My mind has the tendency to give up when things become complicated. And I absolutely don't have any mental resilient and discipline. Everyday I wake up all I do is repetitive things and in the background live in worries. Like what is wrong with me sighs. I do want to change but somehow I'm too ashamed to work on myself because all I keep thinking about is what will my family and society say. What will they think. How will they view me. Like I feel as if I'm putting myself behind in life
