I'm so sorry to hear about your breast cancer diagnosis but you have come to the right place where you'll get info and support.Have you suffered from anxiety or depression in the past?If you have, then stressful situations like b cancer may trigger it again.Or have you only had symptoms of anxiety since starting chemo?If so,then it may purely be the chemo drugs.They sure sent me into a spin. I don't usually get anxious but I did when I got my first breast cancer diagnosis back in 2003.I spent the weekend shaking,crying,heart racing and couldn't eat much.Once I saw my surgeon and a plan was put in place I calmed down.I had a second bout of b cancer in 2010(same breast,same spot)and I was ok with it but broke down into a blubbering mess when I had to start chemo.After I was through the mastectomy and then the chemo,I started on Tamoxifen and this drug made me feel quite low and couldn't sleep(not to mention the hot flushes)So my oncologist put me on a very low dose antidepressant called Endep which really helped. I also try and do something each day that helps me relax like going in my spa and doing deep breathing.Find that" thing" that helps you relax and by slowing down your breathing perhaps your heart rate will come down. But you should talk to your doctor about your symptoms and feelings cos they may need to adjust your chemo/meds.You may also benefit from counselling with a psychologist(at your hospital?)This is very huge stuff you are dealing with so you need lots of support.Blogging/venting on this site about your fears may also be helpful for you.You are not alone here as we have or are going through the same journey and we understand.
