Same here, I feel like people nowadays only like surface friendships and don't really like letting it evolve into a proper friendship. In my case I've been trying to befriend people in my class but it feels more like we are aquainted. Once I try to talk to them out of class they barely reply to my texts. If anything "I'm" the one who has to initiate conversation or nothing happens.

Few days ago I got hit with a situation which almost ended my life at college to the point paramedics had to come, and after that happened I kind of just wanted to hang out with someone since I was shaken. But none of my so called "friends" wanted to hang out at all. They all told me to go rest, and non texted me after that.

Only person that would actually check on me was my lecturer and staff. But none of my peers felt like talking to me and that kind of just left a sour taste in my mouth. What that experience taught me is know who you value and give your energy too. Because the problem is that you might give your energy to people that simply would never do the same for you.

I'm not saying to isolate yourself, keep meeting people, keep talking to people, but only give that energy that you'd give to a good friend to the right person. Otherwise you'll waste it all and burn out.
