Does anyone have chronic anaemia?

My GP has referred me for a two week wait for colorectal cancer, due to me always having anaemia. 

My anaemia is the biggest cause of me feeling so ***,  they haventh given me any iron tabs at all. I feel shattered, drained and this is making me think more negative thoughts cos of how I feel.

Feel so out of breath and just pants really.  Anyone else feel like this? Just want some iron then i might feel tons better!
