Is it normal to wake up almost everyday and feel like you can't be bothered to start learning a language anymore after doing it for a couple of years?

I'm starting to feel like a robot honestly, " oh, wake up, eat, study Portuguese, go to bed" and repeat, I feel like I don't get anything out of studying portuguese, I don't have any real reasons to, I'm not in school anymore, I don't plan on living in Brazil/Portugal, I didn't lose my job because I didn't speak Portuguese, I didn't let my family down by not speaking Portuguese, nothing. It feels almost like I'm a drug addict, and this drug is called Portuguese, and I can't stop, I don't want to, but I dont enjoy it, it just feels like I'm doomed to do this until I die honestly, I just don't get it, I was perfectly happy before, I wasn't sad, I wasn't bored, I didn't feel like something was missing, I didn't have depression, I was good, things were good, I could do anything other than sit in my bed studying Portuguese and I did, but now I can barely make myself exercise for example. It's almost like I'm following a routine, but It's like I'm a robot following a routine and it's killing me, it's like the joy I felt for exercising, playing video games, reading, learning other things, watching movies, talking with people, traveling, following my hobbies, hanging out, literally the joy came from all those things and went to studying Portuguese, It's like that almost everyday, It's like that right now, I don't feel good, I just want to stay in my bed, I don't want to do anything at all, the only thought I have now is " why am I doing this? what am I doing this for? what is this for? It's truly a waste of time, It's retarded, I dont want to do this anymore" but It's truly a retarded thing to talk to someone else about, It's not a problem, It's not a thing, It's nothing, It's something that truly doesn't matter, but It's something that's killing me.<br>Sorry for ranting, I just wanted to know if anyone ever felt like this.
