I hope it's nothing really serious hun hoping the next 3 weeks go by really fast.

Regarding the fatigue, have you had bloods to check your iron, ferritin, haemoglobin levels? I had extreme fatigue in sept 2013 (could sleep 10 hours overnight and have a 2.5hr afternoon nap and still felt like I had been hit by a bus). After having bloods I ended up having to have an 8hr iron infusion in hospital due to anaemia and I'm also on a monthly 50,000iui dosage of vitamin D as (extremely) low Vit D is also a contributor to excessive fatigue.
