Why do I find myself demotivated when I have no exams?

I'm in a mid semester break. No exams for 3 weeks, no assignments, no deadlines. Just pure chill and totally what I thought I wanted. I'm extremely disappointed in how I'm not doing what I say I want to do. I said I wanted to stream, I wanted to be more social, I wanted to do stuff. I'm constantly waking up to alarms. I'm feeling over exhausted. I don't wanna do anything. I'm mad at myself because I SHOULD be doing something. I DID want to do something now. But I'm just so unmotivated. I'm scared I won't be able to be productive for those 3 weeks. 3 weeks!!!
