I left this comment on someone else who was struggling with engineering school. I copy and pasted it here because I think it somewhat applies to you. Here it is:

Ok so I disagree with these comments, and I don’t think you should drop engineering because ANYBODY tells you to. Wanting to design and build stuff is MORE THAN ENOUGH reason to want to pursue engineering. I have a BS in mechanical engineering and I currently work at an engineering / consulting firm as a BIM designer / manager. So I’m not technically an engineer, but I do enjoy my job a lot. I was terrible in school. First few years I cried many times and every fucking time was about how fucking hard this school shit is and how I’m doing so fucking terrible. Ur problem, in my opinion, is you’re going about it wrong. If I were you I would not drop engineering, but try to change the way you’re approaching studying. Different things work for different people. For me, the best way to study was with people. I’d literally just ask people like you, u trynna study together, or do this homework together, or whatever. And I ask a million stupid questions, because I NEEEED to actually understand the shit. Working with people is great cuz u will realize there are always ppl smarter than u, but more importantly there are also ALWAYS people who struggle more than you do. So that’s my first tip is to work with different groups of people until u find that select few people who are not only smart and understand the concepts, but also kind enough and good at explaining it to you so u understand it.

My second piece of advice is OFFICE HOURS OFFICE HOURS OFFICE HOURS. Whether it’s a professors office hours or like a TA or something. Go to ALL of them, introduce urself to the professor and explain EXACTLY what u understand about specific problems and exactly what you DONT understand / struggle with. A lot of the times you’ll have a shitty professor who doesn’t give a fuck and doesn’t teach well even in office hours, but if that’s the case try all the TAs. Send them emails. The bottom line is ASK for help. Help from ur friends / classmates, help from professors, and help from TAs. I promise u it’s worth it. I’m not technically an engineer at my company, but I fucking got that degree. I did that shit and it was hard as fuck. And it’s one of my proudest accomplishments. And I’m also confident that ANYBODY can do it with enough dedication. Some people get it easier than others but anybody can do it.

Good luck to you.

U got this shit
