how do you stop feeling alone?

[Amber]

I have these days where I feel alone and that I need to speak to people, some days I feel so happy and have amazing conversations and loads of people to talk to. other times no one ever seems to be available or it feels like everything dislikes me. I have a best friend that's like a sister but right now she's on holiday with her boyfriend and I just feel really alone, I have a boyfriend also but he's a busy boy we try to see each other as much as possible but it's complicated and it makes it hard to see each other sometimes. I used to have a whole group of girly friends but things happened, we all moved on from one another and now I have about 4 close friends and then loads of acquaintances. So how do you stop this feeling?
