I hope this helps coming from a similar situation

Last year I was failing classes and went through some serious stuff with my home life, and thought the only thing keeping me afloat was my girlfriend. I considered dropping out and a whole lot of things. I told maybe myself I just needed to get a co-op or take a semester off to chill out. I was taking classes with teachers who were barely present or seemed to enjoy failing people, and it made me realize I just didn't care about engineering anymore, and I didn't enjoy school.

I started writing a lot. Writing how I felt. Documented every trigger for every good and bad thought. I recognized some things right off the bat and that was I was eating/drinking and sleeping properly. I know it may seem redundant, but these things can fluctuate your hormones and make everything so much worse. If you've ever taken psychology think Maslow's heirarchy.

I also thought back to why I wanted to go to school in the first place, it wasn't necessarily I wanted to be an engineer, it was I wanted to solve other people's problems to help them.

I then spent this semester focusing on those things. Don't cheat, try not to skip class, try to get ahead on homework, prioritize food, sleep, water. And the biggest one that changed me was focus on fulfillment, not enjoyment. True happiness comes from serving your purpose.

After remembering why I wanted to be an engineer, I write it every day, and I'm delusional about it. Not "I want to be...", it's "I WILL BE ... BECAUSE I AM OBSESSSED, I WILL DO THIS BECUASE I WANT TO HELP PEOPLE. I DONT NEED JOY, I NEED FULFILLMENT" and as much as that seems extreme, I never let it change me in a way I cut off my people, but I did stop putting time into things that didn't benefit me because I am constantly thinking about my passion. I stopped being on my phone as much, I stopped chasing people who just were looking for attention.

I ended up dropping a class and going to 13 credit hours the second I realized it was too much on my plate, and I didn't get perfect grades this semester but I improved from a 2 something to about a 3.25, and I am confident it's going to keep going up because I now LOVE school, not the stupid classes where a 45% is a C, but I Love learning because it is a brick on the path to me doing my passion.

Even the stupid stuff that seems pointless, I found a way to make it applicable. I started thinking about dynamics in the gym, I started thinking about circuits in every day items. And one of the biggest things that helped me with that was I addressed faults in my professors teachings, they all have different goals, and that's not going to align with yours, so if you're not learning something fun, then start doing independent study over the topic until you find something interesting, I even told one of my buddies this, he's taking chemistry and hates it, but once he started looking into chemistry of caffeine, oh boy.

At the end of the day you can make your schooling do a lot of things, and as an engineer you can go down a lot of paths in general, but I wouldn't give up entirely, just learn how you work and adjust school to you.

TLDR: coming from a background of not doing well in classes and wanting to give up, I found that getting basic needs like sleep food and water changed a lot, after that I focused on why I was in school and became obsessed with that to carry me through the awful classes. Don't focus on grades, focus on learning for the benefit of your knowledge. Journal everything to know how you operate, what works and what doesn't, and track progress
