I have no meaning

I'm 17 and I'm already sick of life. Due to health issues I was forced to quit my sport and other things I enjoy. I'm almost in constant physical pain which also leads to mental/emotional pain. No matter what I do there's simply no joy in anything. I've tried so much to find something I can cling onto but I just can't. It doesn't help that I have literally zero friends and am starved from human connection. I hate my family, terrible at school, a disappointment to my parents and have no ambitions or dreams for the future, not anymore. at this point I know it's over for me but I just wanted to let this out
