I am not a particularly funny person so I think surrounding myself with funny people is the key to a good friendship though it's hard to come by someone with the same humour..
You talk, I laugh, that's all I need rn
laugh out loud when you find something funny, don't deprive yourself of the LOL. When I laugh at random times my friends just say 'oh, don't mind her she's just open laughing', you can open laugh too, it's fun, you'll feel better.
Sometimes we are scared since people might not respect that space. But let's give it to ourself first, curled up under our blankets. Just don't fall asleep before you give it to yourself!
