Hello friend. I understand how depression kills you day by day and affects life. So I would suggest you to visit a therapist who will help you to come out of past thoughts. As you have mentioned, you have already taken medicines for the same.but how long are you going to be dependent on them? I understand your past was very painful but you have present and future in your hand. If you want to continue your career and dont want to get married, No problem. Do what your heart wants to do. But please dont carry your past burden on your mind and there is no need to worry or to be negative about married life coz every coin has two sides. I see the positive side of marriage. You may find a nice guy and one day you will have your own family including your kids and these past wounds will fade away slowly. But for that you ll have to give life another chance. Let someone come in your life. Please dont be so negative about your future. You are doing well in your career and once you establish your career think about marriage. Now as you are earning money, you can move in to different apartment if you dont wish to stay with your relatives. Make friends, watch movies, even make boyfriends.. after that chose good one as a your life partner. Basically I want to tell you that do the things ( even though you think they are silly) and you ll feel the difference. If you want to find like minded people then you can join meetup app where you ll get groups as per your hobbies. So explore yourself, make silly mistakes, crack stupid jokes, watch Netflix and eat snacks at 3 am.. these r small things but make your mind feel relaxed. So behave like youth not like aged people in short start life again, dont think too much about your past coz past doesn't define you.. your present actions define who you are.
