Anxiety is trying to return

Yes, that's right my anxiety is trying to return and I do not want it to.  I have been doing so good lately and have been not anxious at all.   But the past two weeks have been very stressful my whole family including myself has had the stomach flu.  It has taken us a very long time to get over the flu.  Both of my sons lost a lot of weight and are now finally starting to regain some of it.  They are both starting to eat although my younger son is still really cranky, I am so ready for that part to be over.   I am worried because today I had a migraine, a massive, massive, massive migraine the kind that makes you nausous, sensitive to light and sound.  I also started to have bowel problems again (hopefully that is not tmi), what has me worried is that that is how the stomach flu started for me last week.  I don't want to start this all over again, because if I get it again that means more then likely the boys will get it as well and I don't think I can handle it.  I know God only gives you as much as you can handle, so I need strength Lord please. Also this has set my anxiety on medium-high, because I start thinking what if it is something more serious then the flu, but masquerading as the flu.  I know that sounds stupid, but these thoughts run through my head and that does not help anything.  Plus there is the whole swine flu thing worries me because they have found cases in my area.  My boys were hit so hard by the stomach flu, they need time to recover before they get sick again.  I pray that no more people get, it sounds nasty, and I don't want it.  Please Lord help us all!
