There is a lot of valuable advice in this topic already.
Let me give you a different bit of advice that has served me well.
The general vector of most of a large number of these posts is do more...do...do...do...
The error underlying this situation is a misunderstanding of the value of your work and your labor. Mostly likely a vast misunderstanding of the value of sleep as well (trust me I've worked past the point of my own safety a few times sleep does matter and often when you least expect it).
Ask yourself something: what were *you* getting out of FIRST that you are not getting out of college that made that hard work worth it?
The value of education is not that number of classes the school could force you to take to justify their bottom line once you declare a major.
As others have said - colleges will often go real easy on you the first year or so then drive you into the ground. This is not just about getting the easy stuff out of the way - it's a great business model to get you as financially invested as they can get you before they have to pay up on their end. Why do you think schools can't often agree on what is transferable between them?
My advice to you is simply this. Use this time while the situation you are in has distracted it's insanity away from you to find out what the real value of your time is. Personally I have told my students this before. I may mentor you in CNC programming but why would I suggest this is the best use of your time when I make significantly more professionally and most often do not use CNC machines to do it? I mentor it because I hope it enables my students to learn, contribute and participate. It empowers them. I hope it opens their heads to new ideas and so when they find themselves in those dark moments when they feel lost maybe they have some ideas on how to fulfill themselves.
I am a guy with an associate's degree from a community college. My Father was a guy with no college degree. Our collective work has built key parts of this World's infrastructure for more than 50 years and is undeniable.
FIRST is an opportunity, college is an opportunity and even war sometimes is an opportunity. I hope you can understand the difference between going through the motions and doing something you really value even if the rest of the World will spend it's time telling you about your faults and limits and doing things that may not be in anyone's best interest.
Engineering is not the only true path and trying to make one size fits all is bound to create negative consequences. The value of FIRST is that it encourages people to see what engineering can be to you before you get pulled back into a college system that makes the most money when you can not complete the programs but you convince yourself that you must have a degree. So you spend...spend...spend on student loans that might even survive you if you die young or in some tragic accident.
Work smarter - not just hard.
Cause slaves work plenty hard and they are still slaves.
So much blood has been spilled so you can have this opportunity to
fulfill yourself, use it wisely.
"Then the joy of achievement when one can successfully take a few steps without falling. The appreciation of people around is a key component of achieving personal fulfilment. It is invariably followed by a sense of habituality (i.e. being able to perform any act e.g. walking, habitually).
Then boredom. Followed by a yearning for the next horizon, whatever it may be for an individual."
