Oh, wow. Good news, bad news.
The good news is that you can go select roses that are the color and size that you really want. Maybe get a thornless one, or a heavily scented one, or something really easy care.
The bad news is, this rose you have, which appears to be a Pink Double Knock Out, certainly appears to have Rose Rosette Disease. There's plenty of info about this disease on this forum, but the bottom line is, when the disease has caused the rose to form witches' brooms (the thorny clusters you see higher up on your roses), then most likely the virus is running through all parts of the rosebush and the only cure is to dig it out, completely, making sure to get all the roots.
There is currently no cure for this disease. Where are you? It is possible the disease came with the roses when they were new, and your area doesn't have terrible RRD issues. Our area is a hotbed of RRD, and I have removed many roses, but I still grow almost 400 with no disease, so don't give up on roses entirely.
I have a hedge of Pink Double Knock Out, and 1 in the center showed symptoms of RRD. I removed that one, and the rest have been clean for the last 2 years.
So sorry to bring you bad news. We can suggest lots of new roses that you could plant! And good places to buy them, too!
