Immediate post-relationship break up anxiety dizzy feelings

Hi there,
I've just had to sign up to the forum purely to post this message to get some support and advice about what I'm going through right now. My partner of 4 years broke up with me last night (after being able to tell that something wasn't right beforehand, I managed to tease it out of him to help us face the truth about what was happening) and today I have just been experiencing the typical break up blues of uncontrolled crying, but I've also kept feeling constantly faint/dizzy and with an elevated heart rate too. I tried to nap due to feeling so rough but just couldn't think of anything but the break up and the feelings of extreme faintness too, almost panicking over how I fee, along with about the break up. I've tried breathing exercises but can't sustain the feeling of brief calm it tries to give me, I just feel like I'm on the edge of breaking down all the time. I do believe I struggle with an 'un officially diagnosed' anxiety disorder as I often feel my heart race and feel faint /dizzy some days and then fine the next. I've had blood tests done at the docs and for the dizziness I was simply once told it was 'post-viral'! And all other tests came back okay (thyroid, diabetes, kidneys etc etc) I also and ECG which came back fine too.
I'm sure that this is all just related to the emotional stress this situation is putting me rough, but it would be lovely to hear what you guys think too? Emotional stress aggravating already symptoms of anxiety perhaps? Any ideas on what I can can I do to help feel better?
I'm sorry for the rambling on,
Love to all xx

Daisydew65,

AWE, you poor thing. :( Seriously, that's the worst. Break-ups are so hard to deal with. If you weren't feeling sad, that wouldn't be normal. It's ok to be feeling so overwhelmed, dizzy, etc, given your current circumstances. I am in a big hurry at the moment, so I can't type much, but just wanted to say to give yourself some time to grieve. I am sure this is a huge disappointment for you, and with time things will come to a new normal.

Sorry my response is so short!

Hi there, thankyou so much for your responses, it's been so so long since I've gone through a break up it's just even more of a shock for my mind and body I think. I managed to get some sleep last night which helped with the dizzy/faintness, and I can't thank you enough for the links to relaxation scaredy cat, I burst into tears when I read your messages just cus it was so nice to feel that support and help!
I've felt a bit better today, but it's so easy to keep thinking of him and how different things are going to be and complicated.
Thankyou for your kind words though, so much xx
