Why are doctors so unhelpful?

So i have been getting a chesty cough for a year now like there's phlegm that I can't get out. So i went to the doctor and he just brushed it off and after that he said i have asthma but I hell know I don't, and im just so angry that doctors don't do their job well , I was given the asthma thing to "expand" my tube to help me breathe better but I don't get how that helps me prevent or get rid of the phlegm that's been with me for a year, the inhaler isn't helping either, plus I wanna save money so I don't wanna get another visit ugh
