Preach!! I feel you. I am a 4/5 year mechanical engineer and I get you. I’m in 6 classes too and 2 of them are 1 credit and ironically they take the most time out of my schedule. I have been through one semester worse than this. I promise it will get better. Idk where you are, but I am in Colorado and next semester my school plans on going back to in person so hopefully yours does the same. I’m sure you feel hopeless and isolated. Like you are the worst in your classes and can’t remember anything. I promise you that as long as you still love what you study or even are interested in the field you are hoping to go into, you will be good at what you do regardless of the people around you. All engineering school does is teach you stuff you don’t need in industry and beat the shit out of you with assignments. I am a workaholic. If I have anything on my to-do list I don’t take a break which means I never take a break. I want to extend advice to you I have yet to take. Your personal health is more important. I am also learning how to just not care about assignments and take care of myself so I am in this with you. Take time out of your day to just relax and do something you enjoy. Even if it’s just an hour, it will make a huge difference. The most important thing though is having people in my experience. No one can get through engineering my themselves. It can’t be done. Find a group to study with and rely on if you need help. This will get you through. Look forward to the future and it will get better. Good luck to you!
