Cant get a full breath in. What would you do?

Basically the last 3 days, every day ive be feeling increasingly worse, I've been struggling to get a full breath in, if that makes sense. I can if I push my arms up on something to get a deep breath i can, but other than that I cannot. I very mildly feel like I'm suffocating. Day 1 I put it down to anxiety, day 2 I put it down to more anxiety about the day before and not being able to get a full breath unless I either yawn or push myself up but today is day 3 and even while playing with my kids and focusing on other things, I'm still struggling. This last afternoon I have felt dizzy a few times and even my daughter has noticed me trying to breathe deeply and asked if I was OK. Other than not being able to get a breath and feeling pretty dizzy, I'm OK. I KNOW my iron is low and I'm having a transfusion tomorrow but I just don't wanna go to sleep and not wake up for my kids sake, if an er trip could help me. I'm in aus, and aboriginal so it won't cost me anything to go but I just want to know if you mummas and beautiful people would head in just to be safe, knowing it's no cost.

Im 27 and did smoke in my younger days if that's any relation. I do have a drs appt next Wednesday that I was going to try and hold out to but I'm just not feeling confident that there is nothing wrong. Help please xoxoxo
