Can Somebody Please Help Me! I'm Almost 19 And I've

Can somebody please help me! I'm almost 19 and I've had vaginal discharge for about 5 years and every test I get for bv, stds you name it it comes back negative. The doctors tell me people have different bodies and it's normal but I know it's not! It's green and thick and smelly and so unhygienic and I can't live with it anymore it's stopping me from doing the simplest things I get a shower an the minute I put fresh underwear on as soon as I stand up it comes out and no matter how much I try to clean it constantly smells. Please help me
