Hi @Sandra01, big breaths.
It is so overwhelming at the start and it does all happen quickly. It's good you have your treatment plan and working through it all. Clots can happen and your treatment team will work out what to do. Some people are put on blood thinners for awhile to help that.
It's a tough road emotionally and we all understand that. Try not to let those thoughts take over. Breathe, walk a bit if you can and keep busy doing what you can to distract yourself. Have you had any counselling? Many of us get that type of help because it is hard to process and it does happen quickly as we go from surgery to chemo and radium. I had a few sessions with a psychologist who understood breast cancer and I found it helpful.
I hope that today brings some peace to you and you can advice from your treatment team.
