Had to make the most difficult decision of my life last year and I'm a much happier person. Even when I was with friends I felt alone, and I was always treated with contempt.
Also what I'm talking about here is that I left all my friends, so I barely have 1 person left to call a friend.
Now I feel like I got rid of a lot of dead weight and I am EXCITED because of all the potential friends I could make now.
Obviously it's harder to meet people when you're out of school, college, university etc. I am a Gamer so I tend to meet people all the time, but, trying to befriend them is a harder ask.
