The circles under and around eyes could be allergy shiners. They can get bad enough to look like a black eye, and can worsen on exposure to an allergen.
The easy bruising could potentially be Ehlers–Danlos syndrome, and inherited connective tissue disorder that causes unusual hypermobility of joints, among other symptoms, easily bruised being one of them. I Know ED has been discussed here before as being common in PWC...I once followed a link to a "self diagnosis" like thing and it was like "ho hum, okay, so according to this I have it....file for later, maybe have a doctor look into it for me someday." I did not have hypermobile joints before my CFS became severe, and as a gymnast at the time I should know. Now my elbows, for example, hyper-extend beyond a 180 degree angle, whereas before that was not even an option.
And I do bruise with nearly every blood draw--the only times I haven't are when I cheerfully challenge the person drawing it to do so without leaving a bruise, and talk about how many have tried in the past but weren't able to. It seems to result in them being extra gentle with my vein which appears to minimize bruising.
