Come to my senses, just need help now.

I think I finally have come to my senses I am depressed I need help, but how do I tell someone close to me I have a mental illness, It’s not like I can ask my mum, she thinks I’m crazy as it is, and I’ve only just moved here so I can’t tell one of my new friends they will probably just laugh at me like my old ones did and leave or bully me. I don’t know what to do any more my anxiety is coming back which means one thing socially awkward. I don’t want to go back to the old me, I promised my self I wouldn’t, and I wont. If only you were here still, standing by me, I could trust you then, now I’m not so sure…
