Loneliness

Guys is it just me or jee phase makes you lonely? I mean the only people I talk to are my parents at this point. Stopped hanging out with friends and all. I’m not asking if this is worth it cuz I know it is but I just wanna know is this normal or something i should work on. People seem to go away from my life so easily and I don’t know how to hold on to people. Like I see people in touch with super old friends but for me as soon as someone goes away from my life it’s just permanent in my case idk why is this happening. Is this normal ?
