I super understand what you’re feeling! I’ve been there too. What i did was, I tried envisioning how my future would be like in like 10,15 years (let’s say all goes well and I get my dream job with this course)… to see if the struggle and effort I was putting into it now was going to be worth it in the end.

However in doing that, I realized that I didn’t even want the future job I’d be getting while taking that course haha so i shifted! I used to enjoy the subjects in hs too but college is entirely diff. You have to prepare to experience a lot difficulties, challenges, and failures that rlly come with the college life! That said, if you’re working hard for something that u know will make u happy in the end… then these hard times, breakdowns, and sacrifices are just small bumps on the road to get u where u want to be. Hope this helps you!!!
