Hi OP -- I'm glad you are working on it. I had horrible acne as a teen and into my 20s and it's so hard. Demoralizing at such a sensitive time in your life. Agree with others to see a derm. I totally get the concerns about accutane. I couldn't take it. I know it is what a lot of people do, but it's not for everyone.
Anyway, I won't tell you what meds to use -- a good derm will be able to figure that out and if something isn't working, or is working but overdrying, they can help you sort that out.
BUT I do want to recommend a product I often rec on these threads because it was a godsend during my years of addressing my own acne. It does not solve acne but it can really help improve the appearance and importantly FEEL of acne-afflicted skin. Acne, especially cystic, can be so painful. Sometimes when treating it, it becomes more painful and inflamed. This product will help a lot to ease inflammation, can help with redness and skin texture. I remember when I started using it, even though I still had acne, it actually helped me to sleep better because my acne hurt less. In addition to using it as intended, as a mask, I would sometimes use it as a spot treatment on a painful cyst or pimple and it would help ease the pain and also reduce it's appearance.
Anyway, here it is:

The reason it's so soothing is the combo of zinc oxide, sulphur, and camphor. All of which can help separately, but something about the combo in this mask is magic. I know I sound like I work for Origins or something (I don't!) but really it's just that I have such sympathy for anyone dealing with persistent acne and I have been recommending this for over a decade because of how much it helped me!
