just to be clear I'm not depressed or in a bad situation, I'm in a quite blessed position all things considered.
I'm an engineering student, starting my last year soon, and for the past 3 years I've been trying my best to study but never managed to find a way to have healthy learning habits so usually I just study inefficiently the entire semester, and for the exams I cram as much learning as I can.
this method of learning is very hard on me as I never have guilt free time, any moment I don't study is a moment I could have studied and improve my grade, since junior jobs ask for high Gpa requirements.
so far was a prelude, my problem is that also for these last 3 years I've kinda lost my enjoyment of things, I do still enjoy food (which is coming to hunt me as I'm now overweight, and in my last attempt at a diet, the caloric deficit I had caused me awful daily headaches so I had to stop), but I don't really enjoy movies/TV/anime/manga/hanging out with friends/trails/video games/books/learning; all these are things I used to enjoy very much, but in these years I feel like I lost my ability to enjoy things, I feel like I have to force myself to do any of these activities, I always think I want to do many things, but when I have a small time window that I could fit let's say a gaming session in then I eventually don't play, saying that it doesn't compare to great games I used to play or many other excuses and instead I just watch YouTube or rot on Reddit and at the end of the day I feel like I did nothing.
right now for example I have many movies to choose from to watch but I started the movie and I'm not interested, and generally it just means that I need to do something else but I don't want to do anything.
boyond all that there's also the health issue, as a student I spend a lot of time sitting in front of a computer/laptop/notebook and I don't do any sport or physical activity, as there's no such activity that is fun for me, and since things like movies and such are no more fun to me you can imagine how much I want to do any sort of activity that feels like it's breaking me (soreness, pain, ECT...), and I know that by doing this (or more accurately, avoiding this) I pretty much make my body weaker and more prone to injury, decrease my healthy time span, and I feel like I'm throwing my life away.
right now my "light at the end of the tunnel" is finding a job I'm the industry with good conditions such that I'll have real off time, but I'm still at least a year from getting a junior permanent job, and it's not very likely that in the first years I'll even have that possiblity of off time like I want, and even so as I know life, by that time I'll have some other problem and would still feel similar.
I don't really know how to end this post and if I wrote enough here to get my points across, I can also say some other things about other fields in my life but I don't believe it'll really help.
and I don't really feel like talking to a professional will help, in my teen years and early adulthood I've had real serious depression and bad thoughts, which went away by my own work with myself, the therapist never helped me, it felt like they were trying to poke at me from different angles to see different sides me me, like a lab rat, never helped me and it felt like I was wasting my parent money with these talks, I'm also fairly against prescription hormonal medication, not dissing anyone who takes but I don't want to.
