How to be independent when you lost friends?

[Jake]

Keep your head high. Walk with confidence. Even if it's just a mask, it'll show other people that you're doing good without them... This will attract new people into your life. You keep trying, maybe you'll meet some people who have similar interests to the real you. The biggest thing is not to sulk in it. If they looked like they've moved on and gotten new people in their lives, the best thing to do is that. As for staying actually happy, if you can, get closer to your family. Get closer to the friends you do have. Find things you enjoy doing that make you happy, and do more of those things.
