Seeking help for depression

So for as long as I’ve know I have always had a battle with depression but it seems to get worse as I get older and I’ll be honest I’m tried it beating me down and I can’t take it anymore. How do I get help I’m not really in the position yet to tell my mom I’m 20 and live with her but we don’t have that relationship I just want to see a doctor but not to sure how. Do I just go to my primary doctor and do I have to see someone else. I just really need help please
