Two things come to mind to me, priorities and enjoying what you're doing.
First is priorities. They seem to be focused on future sucess. You seem to be focused on paying off loans (current job) and education (to get a better job) so you're focusing most of your time on work. That's going to stress you out. However if this future goal is so important to you then maybe it's worth it. If it's not then why are you so focused on it, and not on other priorities in your life. Do you know what your other priorities are? How much time are you spending on them? Are they less important than what your education and current work related priorities?
Second enjoying what you're doing. I've found that since I enjoy what I do for work, and the impact I make that sometimes when I work a longer work week I enjoy my free time activities even more, because I have less time for them. Example: Reading a book. On the weekend I could read an entire book and only have enjoyed it for 1-3 days time. However if I'm busy and only read a few chapters a night I could have weeks of enjoyment from that same book. I can be at work and be excited to read a couple more chapters. It can get me through the day with excitement I wouldn't otherwise have if I had read the whole thing in a few sittings. If you make time for a weekly event it can make you more excited during the week and days leading up to it. Such as weekly Rock band night, weekly bonfire, weekly potluck dinner with friends, weekly movie night, etc.
In short I think you're putting too much energy into your work, and less on yourself and leisure. Is this what you want? It may help make your future less stressful, and that may be worth it. If you change your perspective then maybe that'll be enough to make it worth it. If it's not then maybe you should reassess how you're spending your time and how it relates to your priorities. If you're just working a ton now, so you can graduate and work a ton, then what's the point? It may never end. On the flip side of the coin, almost all times you've got to work hard to get what you want, if it came easy no one would work hard.
TL;DR Reassess your priorities, what they are and if you're spending your time on them appropriately.
