Losing Interest?

I’ve been very confused with myself lately. This has been ongoing for probably 2 weeks already and it was over the weekend that I realized something shift inside me. For reasons inexplicable, I just don’t feel excited or motivated to socialize or hang out with anyone even close friends regularly nowadays. When I interact with people on campus, I am able to mask my inner feelings with congeniality or jokes and can be very talkative with others; however, whenever I am left on my own, I just feel like I could go on for eternity just not socializing— I desire to isolate myself. To be alone. The idea of fostering new and already existing connections has become something dreadful to me. It’s as if I have become socially lazy

I also have a boyfriend of 1 year who I hang out with on a regular basis, and I can’t help but feel that I am starting to be exhausted and unenthusiastic seeing him. It’s a feeling that has been bugging me since Friday. Earlier I had dinner with him, and I felt nothing with him. It’s been this way for three days already. There was this thought that emerged that I simply would be indifferent if I didn’t speak to him for weeks or months. It’s heartbreaking because I never anticipated I’d feel nothing towards him along with the people close to me. People say the honeymoon phase dies eventually as it’s a normal thing that happens when you are committing to someone, and see them regularly. I just think my depression is manifesting again. This semester has been very heavy for me academically, and I also lost interest in my hobbies. I’m so fixated on studying to boost my GPA to that extent that when I’m not doing anything related to academics, I either sleep for long hours or just endlessly scroll on my phone numbingly. Disappointing
