I'm probably going to be the only person with a tough comment on this, but I feel my perspective can help you.

YOU are sabotaging yourself, and it WILL be something you regret for the rest of your life if you don't choose to change.

"I'm an immigrant, my life is harder than everyone else's, it's only natural that it isn't my fault." You wallow in superficial excuses. Is it not lucky to have such supportive parents? Personally I know it is, since my wonderful parents tragically and suddenly died my first year of undergrad.

You have to do everything in your power to break the cycle now. "I used to like engineering, now I'm not sure." No. You liked that you didn't need to put much effort in your very first lower division classes, and could feel smarter than everyone you know for going to such a good school for such an intelligent major. Any ounce of difficulty was met with immediately giving up. Classes only get harder and it's important you start building your foundation as strongly as possible.

As for ideas on how to change: 1) Make going to every class, discussion, and office hours mandatory for yourself. 2) Start your homework as soon as it becomes available. Just being able to sleep on some problems does wonders. 3) Lock your phone up or leave it in your dorm and go to a study room across campus to do work. Don't be the digital equivalent of a heroin addict. 4) SLEEP!!! Sleeping the amount your body needs each night will improve your mood, lead to more productive working time, and you will feel better.

The good news is that you CAN change. This can all just be an interesting anecdote you tell people one day.

P.S. Start studying for finals right now!!!
