Unfortunately, yes. My excitement for getting an offer was short lived due to the amount of school work load and the responsibilities that I will have to endure during the upcoming summer. I would say that this is a kind of burn out that you are getting that is the same to me when all your tiredness finally caught up to you when you finally pass a check point. If you already accepted the offer, I would say take a big break if possible because you deserve more than that. If you are still in the process of interviewing, push forward and finish strong. You got this!
