I'm a comp sci major too! how do you like it? It is a pretty tough, niche major and I can see how someone would be unsure about it. But it's very flexible and you don't have to do software engineering. I gave up my dreams of art school due to my mental illness so unfortunately I can't really relate to your situation. My family is also not privileged or Asian so the standards for me were low. But understand you are in the same position as millions of other students. Everyone gets thrown into adulthood. I've had to learn about taxes and bills on my own and trust me it's not gonna make you feel any less "immature." You'll just have different thoughts and feelings, like what if I cant pay this, what if I did this wrong, etc.
Just wondering, did your family ever describe you as lazy and a baby? Or make you feel that way in their actions? I noticed a lot of people from high-pressure and privileged families feel like you do because there's such a big pressure to perform. But then the people in their life don't do anything to help them adjust and grow. In fact they sometimes limit it purposefully, sometimes by helicopter parenting, by being straight up demeaning, or not caring at all. In the end it's not your fault and probably you've internalized their expectations of you. But it's your life, you can do what you want. And there are lots of very good, steady jobs that you can get by working your way up in a business. No degree required.
If you want to be independent you have to take the necessary steps. Sometimes it will involve failing. But if you can have a good support system outside of your parents, even if it's just a good therapist, that will help ypu feel empowered to take risks and realize that most of the daily tasks of life are not impossible or scary, even if you have more needs than the average person.
It's really good that you're holding out at least and giving it your best shot. I hope things can start looking up for you with the different therapy and a change in pace once you graduate. But whatever happens you have people who will listen to you on here without judgement. If you can let it out that might be all you need when you're feeling shitty. I'm sending peace your way ♡
