First good for you being strong enough to go and visit your boyfriend when you knew he was sick. That is a positive step towards taking control of your phobia! Pat yourself on the back for that!! You could have stayed away until you knew he was well and you didn't! WTG! Now I doubt HIGHLY you will catch anything from him. Typically you catch the bug from using the same food/drink utensils behind a sick person or not washing properly after using their restroom facilities where they've been sick. You didn't touch anything he was drinking from and you did wash properly after you were in the house. Just toss your clothes in the washing machine with a little bleach (not enough to dye anything) in the water, use the hottest water you can and then dry them at high heat if you are worried about lingering germs. As hard as it is, don't spend every second obsessing about it. Get out of your house, go outside, get some Vitamin D from the sun (good for your immunity), take a walk, don't sit around and worry. Stress weakens your immunity, so don't let it! And again WTG on being a good girlfriend who can put her biggest fear aside for her man!
