Hi please help! (I'm new here by the way.)

I'm 15 and I've had acne for about 4-5 years now. I'm so sick of it! Everyone around me has perfect skin and I'm just stuck with ugly acne on my face. ): I currently have active pimples, but they are somewhat getting better; I don't have as many as I did before. But literally after every pimple swells down it leaves a mark!! Now I'm stuck with horrible discoloration + pimples on my cheeks. And it looks so gross! All of the scarring and acne is cluttered all over the place. It really brings my self esteem down. I already went to a dermatologist and she prescribed me both oral and topical medication, which neither have worked for me at all. I'm really struggling with this and I can't stop thinking about how bad my face looks. Also, I know this is bad for my skin but I pretty much wear makeup everyday because of how bad it is. I feel uncomfortable being around anyone without some sort of foundation on my face. I make sure to take off my makeup throughly at night though. I'm sorry it's kind of long, but I'm really struggling here. Do any of you have tips or advice? Please, it would really help me.
