Can’t function

Hi everyone. First time posted. A few weeks ago I saw a doctor for a breast issue. Had scans, everything was normal. What do I do then? Well, I haven’t checked the other breast in a while! I dug until I found something. Went to NP, who said everything was normal but since I have a lot of anxiety around my breasts, why don’t we get imaging on this breast so I have a baseline going forward when I do self exams. The appointment was supposed to be tomorrow, but a combination of the bad weather where I am, different location far away, but mostly my own anxiety caused me to cancel. I rescheduled it to a location near me that I’m familiar with for a few weeks away, and now I’m so upset at myself for doing that. I just know this location and how it works better, and I just couldn’t handle going tomorrow. I’m trying to tell myself that this isn’t even a scan for a particular concern, just for peace of mind, and that when I DID have a true concern, I did go right away. I have been stuck in horrid anxiety for weeks and just want some relief. Every day I wake up crippled with anxiety. It gets better in the evening. This week I took two days off just to sleep bc that’s the only time I feel comfort. I take meds and see a therapist. I just needed to get this out of my own head.
