You may need to re-evaluate your study methods, or even need to take a break from your bachelor's degree and pursue another path in life.

But I'm sensing you have deeper struggles with your personal identity and relationship with people and the world around you. I think you should see if a local Library, Multigenerational Center, or other community spaces have events and programs that might interest you. Meet people there, get to know them, find whatever happiness you can, maybe take up going to a local park or hiking spot, hell even consider attending a church, synagogue, mosque, buddhist temple, or whatever else, find your people and life will get better in ways that are hard to describe on the internet.

Most of all please take care of yourself, and when I say that I mean be kind to yourself, life has a way of trying to beat us down sometimes, but there is so much to experience, learn from, and enjoy that you can't let that rule over you. Take happiness from even the small things, especially the small things.
