need a little support

I'm going through a tough time right now. Without my boyfriend, who is my best friend, I feel so alone. And I can't be with him 24/7. I'm not connecting with any of my friends atm. I'm in my last year at school so I'm feeling the pressure. My mum just constantly yells, makes me feel like I can't talk to her. Things just suck. I want to scream but I feel like no one will hear me
