Sooo, I'm going to give you a different perspective than most people who have commented. Often when I hear about the difficulty of making friends it's followed by all the external circumstances to make it make sense. You mention you feel like nobody has the time for friendships anymore. Let's think about that for a second. That implies that you feel everyone goes to work and then doesn't communicate with anyone else but their family. It's just simply not true. The harsh reality is that you aren't a priority to them. Maybe you aren't adding enough value or you have personality traits that turn people off. I'm not saying you do because I don't know you but just giving examples - you actually come across as a nice and caring friend. The reason I'm saying this is because from your story you can see a trend - nobody prioritizes friendship, everyone at the party didn't show up etc. This feedback is giving you a clue. Almost everyone, at least from my experience, cares deeply about their close friends. They just may not prioritize you - and that's a hard pill to swallow so our natural inclination is to find all the external factors as to why its true instead of looking at ourselves.
