I am afraid of aging and not living my life the way I want

I am 23 years old. I have recently completed my masters and now i am looking for a job so currently I am unemployed and it's always the same routine, wake up in the morning do some chores, eat, sleep, apply for jobs. Days are passing so quickly without even realising that a month has been passed. One day I was just sitting and doing nothing, a thought crossed my mind that soon this year will be over and it will be my birthday in a few months and I will be 24 years old. I can't explain that feeling in words. I wasn't excited for the future, I was sad and afraid. What if I can't achieve the things that I have always wanted. I went to a boarding school when I was 11 years old and since then I have been living away from my parents and doing everything on my own. I don't share anything with my family, for me now it's just uncomfortable even when I visit them I can't live more than a month with them. I just need my own space. I have a lot of friends from my boarding school, college, online friends and I am really grateful that they were there for me whenever I needed but i don't like to overshare with them as well. Whenever I thought about my future I always envisioned me travelling to the different places, trying different food, living away from home owning my place but i never thought about getting married, living with my parents, not getting a good job, not earning enough money to support myself and make choices for myself and suddenly the reality crashed down over me that I will be 24 years old in few months. I am from a small town where girls get married in early twenties, you will not be able to make choices for yourself if you can't support yourself so now the question is that will I be able to live my life the way I want ?
