Gradually realizing that I might have some mental health issues, maybe depression or something similar.

I'm a Senior Technical Consultant at a Big 4 MNC with six years of experience, working from home. I have been living in my hometown (literally a town) and working from home since COVID (March-2020). For the last four months, I've noticed that I've stopped my morning exercise, which I had been doing regularly for the past two years. My smartphone screen time has increased to the extent that my daily average is 8-9 hours, sometimes reaching 11-12 hours while working at a full-time job. I barely work for 1-2 hours at my job now.

I've been lying in bed the entire day. I no longer focus on my work—I’ve just left it. I do the bare minimum, barely finishing tasks, and it takes me twice the time it should. I've been working here for 3-4 years and have a good rapport with management, so they aren’t too strict with me and still trust me as I have been a good performer.

I don’t want to interact with anyone, not even my friends. I keep using social media—Instagram, YouTube, Quora, Reddit, X, etc.—without any specific purpose. I just keep scrolling, and my mind keeps overthinking. I don't even remember what I did during the day, but I keep staring at my screen, unintentionally scrolling, without being aware of what I'm doing. I don’t want to learn anything at my job, nor do I feel like sitting in front of my computer. Everything seems to be falling apart, and I can't understand why.

Now, in this mental state, I find myself turning toward spirituality. For the past two weeks, I've been listening to spiritual content and exploring different perspectives. Sometimes, I feel like leaving everything behind and staying somewhere peaceful.

In the last four months, I traveled to Bangalore for two weeks and Himachal for one week and took four weeks of leaves and stayed at home because I just didn’t feel like working. I want to explore life, and maybe I’m exhausted from my current job. I was planning to go to Rishikesh and Banaras last month but couldn't go due to the cold weather. I am again thinking going there and stay for few weeks. One year back I went to rishikesh and that was a wonderful experience.

What could be the cause of this, and what should I do to deal with it?
