Hi everyone, sorry if I have posted this in the incorrect place, I wasn't sure where it should go...

I know that most people probably react in this way but wanted some reassurance as I'm making myself ill with worry.  
 

Last week, I found a lump in my right breast. It feels hard, smooth and doesn't move when I press it. I went to my doctors and she said there were positive signs that it's cystic because it's smooth but didnt know so referred me to the 2 week breast clinic. Since that time I have hit google hard (I know!) and convinced myself it's cancerous because I keep reading that cysts move - is this always the case from ladies on here experience? For the past 3 days I've felt really unwell. I've taken a covid test so not that, but I feel like I'm hot and clammy all the time. My eyes are sore and I feel light headed and dizzy. I didn't have these symptoms when I saw my doctor so haven't had the chance to mention them. I am so scared and freaked out. I am 39 with no BC history in the family that I know of. I had implants about 8 years ago so also wondering how a mammogram will work and also if they might be the reason - could they be leaking and causing me to feel unwell? Or am I just really stressed and anxious and making myself feel like this? 

Sending lots of luck and best wishes to everyone going through tough times on here. ️
