It’s OK to cry from time to time. But every night might be too much. Chin up.
You can pull your grades up with a little help. Talk to your teacher. See what you’re missing. See if there are supplemental resources for you to help with understanding. A little struggle in Physics is pretty common. It’s still early in the year.
Don’t give up on your goals for EE. You sound like a great candidate for the major.
Good luck!
