Gave my final exam and have mix feelings

So today I gave my final exam of my engineering and within a blink the journey of 4 amazing years came to an end. It feels like it was just yesterday when I took admission in college. Now I am doing an wfh internship and I am feeling like I will be lonely, since I don't have any friends apart from college (which I am pretty sure there are less chances of meeting as I had lot of friend but I was close to none🙂). Earlier I used to go to college and I was kinda a known personality, but now as it is ended so no more going to college and thought of working from home all day is making me anxious and depressed. So want advice from you guys about what should I do, how did you tackled this phase? I know I might sound cringe and sorry for that, but I am writing this just for help and advice.
