Crippling health anxiety

I started Yaz about two weeks ago with the purpose of fixing my hormonal acne, which it is doing a great job at. I haven’t had any other side effects except for the crippling anxiety specifically regarding my health. I’ve always been a hypochondriac and was diagnosed with anxiety at a young age. I’ve learned to manage it with coping skills and medication but recently it’s been so bad to the point of panic attacks. I get sick quite a bit and I convinced myself the last time I was sick that I had lymphoma and I was going to die. I obsessively feel my neck to the point of it being sore and every bump on my neck sends me into a complete panic spiral, even though I know I am fine. My life is being consumed with my thoughts telling me I am going to die of some horrible rare disease that I KNOW I do not have, I can’t even go out and enjoy time with my friends without going to the bathroom and feeling my neck in a mirror trying to find bumps I do not have. Does the anxiety ever stop? Every other experience has been so pleasant except for this, which makes me REALLY not want to switch BC, but if it will help with the craziness maybe I should. Any advice is so so so appreciated :)
