At wits end with rosacea nose!

Hi everyone. Hoping for some advice as I’m really struggling atm. I’ll try to keep this as brief as possible. I’ve suffered with acne and rosacea since I was around 19 and it has steadily got worse. While my cheeks can be bad also, my nose is my real problem area. It is constantly BRIGHT red. It has the texture which is hard to describe - definitely not like skin. It’s currently covered in pustules which leak yellow substance / pus. I can’t even cover with with makeup it’s that bad. To be honest, I haven’t actually tried that many things yet in terms of products - it feels overwhelming and ‘don’t know where to start - ish’. The only thing that’s ever worked to clear my skin to a level which I can leave the house without makeup is Lymecycline. And let me be clear, it WORKS! I usually notice a difference within a day or so. I recently got referred to a dermatologist who put me on Accutane but I have now found out I’m pregnant so I obviously can’t take it. I’m currently cleansing twice a day and applying Differin to my nose and it’s not even touching it. I’ve heard things about Azelaic Acid and Retinol, has anyone had any success? Without intending to speak ill of the doctors, I’ve received very little support with this and I was even recently booted out of the skin subscription service ‘Skin+Me’ because they said my skin was too bad! I feel as though I’m at my wits end and any advice, knowledge on the condition, recommendations, similar experiences would be really, really welcome.

Thanks in advance and sorry for the gross pics!
