You don’t owe anybody anything, just survival and freedom for yourself and that’s it. You can take care of others only after you are safe and content.
To give an analogy, in case of an airline emergency, you put your mask on first before you help others. You are only responsible for yourself and not others. But if you are all set, then sure you may help others and it is encouraged that you do, but not a responsibility.
Of course, you are the only protagonist of your movie and you must chase your destiny. You must follow your heart, and you must be honest to yourself, and you must chase with all your might, and if you’re lucky, you might find who you really are and what it is to be human, and only then do you find out what everyone else is and what humanity is all about, and only then do you find your purpose in life.
