I know this is a common thing a lot of share on here... But I'm really struggling today. Yesterday I woke up in the middle of the night gasping for my breath like I'd just been winded and today my chest feels really tight across the bottom (under my boobs) and I feel so lightheaded. I've been doing really well and this has set me back big time. To make things worse I'm actually in the Spain and scared to fly home later as I'm convinced there is a blood clot in my body causing this.
