I've been burned out twice. The first and deeper of the two was right after I graduated years ago. It made the whole process of going straight into the workforce bittersweet, as I was mentally not ready to muster the energy to endure the rigors of professional development on-boarding for a new grad. I managed, but no where near at a potential I could of been. A brutal semester of final projects and endless nights had left me somewhat poisoned, so to speak. It caused the recuperation of my mental and physical state to be much longer (over a year) than if I took a 2-3 week vacation like I should have done, I imagine. I've always taken this as a likely scenario for a new grad when being brought on within a company.
The second, like the author, was when I was gung-ho into a new technology and went at personal projects endlessly for a solid 12 months before I came up for air and took a breather, with similar but more superficial effects than the first burnout.
I regret these mistakes, and I've learned the hard way to do work in moderation. However, I am not an entrepreneur for these very reasons, and I simply don't want that lifestyle for the long-term. I'm hoping my health will thank me 30 years from now.
It's much easier to back away and recharge when you're close to the edge than after you've already fallen off. So you should try and stop falling off if you can. Take a real break after you graduate, if you can, it'll help. Otherwise consider if you can last a few months at a new gig, that ought to supply you with enough savings to take the same amount of time off if not more and then look for a new gig.
I was excited to start working properly after school, regardless of what I worked on, it would be something that mattered enough that I'd be paid for it instead of paying myself. I started interviewing mostly after graduation and while it was stressful (must find a job soon to pay bills, and start paying student loans) I landed one after not too long. I was fortunate that my start date wasn't until a month after acceptance so I was able to chill for that whole month and really unwind after the stress of years of school. Looking back I was telling people during interviews that I was basically available to start "immediately" (because I wanted more money immediately) but I really should have pushed for at least a few weeks lead time before starting in all cases instead of lucking into it.
I recently came back from a 2 week vacation of just chilling, it's lifted a lot of work stress that has been accumulating. But some times I've entertained myself with calculations about how long I could go financially if I quit tomorrow. I even did that at the start more for fun than stress relief, since suddenly every two weeks you're getting a paycheck that covers 3-6 months of expenses if you keep your college lifestyle. It doesn't take long to save up for a year of goofing off and then a couple months of runway to find a job after that.
Talk to your manager - let them know. The first thing you should learn upon entering the workforce is the power of communication. Most people want their employees to do well, because it helps them.
In addition to what another commenter said about communicating: We (your manager and more senior colleagues) understand that you're just starting out. We don't expect you to know everything. We don't expect you to learn everything all at once. This one probably stings (if you're like me), but can be helpful to your psyche if you can overcome your pride and internalize it: We don't expect much from you at all yet, certainly far less than you expect from yourself.
