I think i’m depressed.. but idk if my mom will believe me.

I’m 17 and I think i’m depressed. I don’t wanna sound like those tumblr girls who think its romantic to have a mental disorder. I want help. I don’t want to feel like this anymore. I miss being myself. I want to talk to a doctor but i’m scared my mom won’t believe me. I have this friend that my mom hates and I’m sure shes just gonna say “oh I bet it’s *friends name* fault”. I’ve never felt so alone in my life.

My question is, is there anyway I can get help and see a doctor without my mom getting involved? I live in canada if that makes any difference.
